LED PCB Assembly – Hitech Circuits Co., Limited

What is the LED Circuit Board assembly?

Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.

We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

Types of layers for LED PCB Assembly

Normally, the base layer is made using aluminum alloy metal.

This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat.

A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics.

It is highly heat resistant and protects the PCB against heat and mechanical stress.

The circuit layer, which is covered by a copper foil which can range from one to ten ounces.

LED Board type- single or in panel

Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time.

Some LED PCB Assembly is done on a single board while others are done on panel boards.

In the LED industry chain upstream of the epitaxial wafers and LED chips accounted for 70% of the profits of the whole industry, and technology-intensive, capital-intensive, where the core technology of the LED. Well-known epitaxial wafer and chip production enterprises will be exhibited a number of energy-efficient, low heat, cost-effective LED products, many of whom have excellent products of international advanced level.

What are the requirements for transportation packaging PCBA products?

After the PCBA is produced, we need to transport it to the customer's hands through various means. During the transportation process, we need to pay attention to the following requirements.

1. Packaging materials

PCBA boards are relatively fragile and easily damaged products. Before transportation, they must be carefully packaged using bubble wrap, pearl cotton, electrostatic bags, and vacuum bags.

2. Anti static packaging

Static electricity can penetrate the chips in the PCBA board. Since static electricity cannot be seen or touched, it is easy to generate. Therefore, during packaging and transportation, anti-static packaging methods must be used

3. Moisture proof packaging

Before packaging, the PCBA should be cleaned and dried on the surface, and sprayed with three proof paint.

4. Anti vibration packaging

Place the packaged PCBA board into an anti-static packaging box. When placed vertically, stack no more than two layers upwards, and place a stopper in the middle to maintain stability and prevent shaking.

Notes on BGA Design in SMT Processing – Hitech Circuits, PCBA manufacturer

BGA layout design requirements

(1) Layout as close as possible to the transfer edge of the PCB, as deformation is relatively small during soldering.

(2) Try to avoid layout at the corners of L-shaped boards and near crimping connectors as much as possible.

(3) Try to avoid front and back mirror layouts as much as possible. If this layout is necessary, the PCB thickness should be ≥ 2.0mm. This is mainly considered for long-term reliability, based on the research conclusions of multiple well-known enterprises. The reliability of mirror layout BGA is reduced by more than 50%.

(4) PBGA should avoid layout on the first assembly surface (first welding surface, bottom surface) as much as possible.

(5) BGA should avoid layout near the separation edge of the layout as much as possible.

How to control the quality of SMT reflow soldering?

What is SMT reflow soldering process?

The SMT reflow soldering process is achieved by remelting the pre distributed paste like soft solder material on the printed board pads, to realize the mechanical and electrical connection between the surface assembled component solder ends or pins and the printed board pads through soft soldering. The technology of SMT reflow soldering is not unfamiliar to us in the field of electronic manufacturing. In our electronic products, components on various boards must be soldered to the circuit board through SMT reflow soldering process. The advantage of this process is that the temperature is easier to control, oxidation can be avoided during the welding process, and the manufacturing cost of the product is also easier to control. This device has an internal electric heating circuit that heats nitrogen gas to a sufficiently high temperature and blows it towards the circuit board where the components have already been attached, causing the solder on both sides of the components to melt and bond with the motherboard.

Optimization methods for high-quality SMT processing, reflow soldering production processes

1. It is necessary to establish a scientific SMT processing reflow soldering temperature curve and regularly conduct real-time temperature curve testing.

2. Welding should be carried out according to the welding direction during PCB design.

3. During the welding process, it is necessary to prevent vibration of the conveyor belt.

4. The welding effect of the first printed circuit board must be checked.

5. Whether the welding is sufficient, whether the surface of the welding point is smooth, whether the shape of the welding point is half moon shaped, the situation of solder balls and residues, and the situation of continuous welding and virtual welding. Also, check the color changes on the surface of the PCB. Adjust the temperature curve based on the inspection results. Regularly check the welding quality during the entire production process.

6. Regularly maintain the SMT reflow soldering process. Due to long-term operation of the machine, organic or inorganic pollutants such as solidified rosin may adhere. In order to prevent secondary pollution of the PCB and ensure the smooth implementation of the process, regular maintenance and cleaning are necessary.

Precautions for maintenance and operation of SMT reflow soldering equipment:

1. It is necessary to establish a maintenance system for SMT processing reflow soldering equipment. After using SMT processing reflow soldering, we must do equipment maintenance work, otherwise it will be difficult to maintain the service life of the equipment.

2. Daily inspection and maintenance of various components should be carried out, with special attention paid to the conveyor belt to prevent it from getting stuck or falling off;

3. When repairing the machine, the power should be turned off to prevent electric shock or short circuit;

4. The machine must remain stable and not tilt or exhibit any instability;

5. Regularly clean the SMT reflow soldering furnace, mesh belt, and condenser, and develop weekly, monthly, and quarterly maintenance plans to ensure the quality of SMT reflow soldering.

What is the testing principle of PCBA?

PCBA testing is a key step in ensuring production and delivery quality. It refers to the production of FCT testing fixtures based on customer designed testing points, procedures, and steps, and then placing the PCBA board on the FCT testing rack to complete the testing process. The testing principle of PCBA is to connect the test points on the PCBA board through an FCT test stand, thereby forming a complete path, connecting the computer and programmer, and uploading the MCU program. The MCU program will capture the user's input actions (such as long pressing a switch for 3 seconds), and through computation, control the on/off of nearby circuits (such as flashing LEDs) or drive the motor to rotate. By observing the voltage and current values between test points on the FCT test stand, and verifying whether these input and output actions are consistent with the design, the testing of the entire PCBA board is completed.

What are the requirements for transporting and packaging PCBA products?

After PCBA production is completed, we need to transport the PCBA to customers using various methods. During transportation, we need to pay attention to the following requirements:

1. Packaging Materials

PCBA boards are relatively fragile and easily damaged products. Before transportation, they must be carefully packaged using bubble wrap, pearl cotton, anti-static bags, and vacuum bags.

2. Anti-static Packaging

Static electricity can damage the chips in the PCBA board. Because static electricity is invisible and intangible, it is easily generated. Therefore, anti-static packaging methods must be used during packaging and transportation.

3. Moisture-proof Packaging

Before packaging, the PCBA surface must be cleaned and dried, and then coated with conformal coating.

4. Shock-proof Packaging

Place the packaged PCBA boards into an anti-static packaging box. When placing them vertically, stack no more than two layers on top, and place spacers in between to maintain stability and prevent shaking.

PCBA Processing and Production Anti-static Requirements

PCBA processing frequently involves various electrostatic-sensitive electronic components and processes requiring specific electrostatic protection. Therefore, PCBA processing must adhere to certain anti-static requirements. Electrostatic warning signs are primarily used for posting, hanging, and placing on factory premises, equipment, components, and packaging to remind people of the potential for electrostatic discharge or electrical overload damage during operation.

Workshop Anti-static Requirements

Based on product production level requirements, the production workshop should be equipped with appropriate anti-static facilities, with independent and reliable grounding. The workshop should maintain constant temperature and humidity. Electrostatic safety work areas should be designated and clearly marked with anti-static warning signs.

The external grounding system should be tested annually, and the grounding systems of workshop floors/mats, workbenches, etc., should be tested every six months, with corresponding records kept.

The temperature and humidity within the workshop should be controlled at (25±2)℃ and 65%±5%RH, respectively; measurements should be taken twice daily, and corresponding records kept.

Employee Electrostatic Discharge (ESD) Protection Requirements

Employees must wear ESD-protected clothing and shoes when entering the ESD-protected area.

Before handling ESD-sensitive components, employees must wear grounded wrist straps or foot straps and pass the corresponding ESD test.

Items that easily generate static electricity are prohibited from being brought into the ESD-protected area.

The handling, storage, and distribution of ESD-sensitive components must be done within ESD-protected packaging.

ESD-protected packaging may only be opened after appropriate ESD protection measures have been taken.

Trolleys and shelves used within the ESD-protected area must have proper grounding devices.

ESD-protected clothing and shoes must not be worn outside the work area and must be cleaned regularly as required.

Cleaning of ESD-protected work surfaces must be done using cleaning agents approved by ESD protection personnel.

Avoid placing ESD-sensitive components and circuit boards with plastic products or tools (such as computers and computer terminals).

Ground all tools and machines.

Use ESD-protected table mats.

Employees without wrist straps should not approach the ESD-protected workstation.

Immediately report any potential ESD-related damage.

Precautions during operation:

Before handling components, touch the work surface with both hands to allow static electricity from your hands to be transferred to ground through the anti-static surface;

Place components with leads downwards on the anti-static surface;

When handling integrated circuits, grasp the body of the circuit, not the leads;

When handling electronic components, hold them by the edge of the PCB, avoiding direct contact with components or board traces;

Do not drag or slide electronic components on any surface;

Keep non-conductors at least 1 meter away from the ESD-safe work area;

Only remove components and circuit boards from their anti-static packaging within the ESD-safe work area;

Store temporarily unused ESD-sensitive components inside anti-static capacitors or in their packaging;

Minimize the number of times components are handled.

Electroplating Conditions for Rigid-Flex PCBs

With the continuous development of PCBs and the diversification of their applications, the trend towards lighter, thinner, shorter, and smaller designs has become the mainstream. Simultaneously, from a design perspective, high integration, high-level layering, high-precision circuitry, and smaller apertures with high aspect ratios are the future development directions for PCBs.

While research on electroplating is abundant, research on software-based design of electroplating conditions, processes, and parameters is almost nonexistent. Industry researchers generally focus on the programmed automatic control, automatic addition control, and stability development of plating solution components for electroplating lines. Due to the differences in equipment types, service life, and maintenance methods among various manufacturers, it is impossible for industry researchers to develop a universal program. Therefore, based on the manufacturer's own characteristics and the analysis of process capability research data, an automated program design suitable for a single manufacturer has been developed. According to the characteristics of the printed circuit board itself and customer requirements, the current conditions, electroplating line type, and auxiliary thin copper process are designed at the design end. This designed information is reflected on a process card, and production staff only need to follow the information on the process card to perform operations.

This paper starts with the post-processing etching affected by electroplating, and uses Minitab software to study the etching process capability. Electroplating copper thickness data for each electroplating line was collected through simulation experiments, and the electroplating efficiency of each line was calculated after data analysis. Simultaneously, simulation experiments were used to capture the different plate thickness-to-diameter ratios and the deep plating capability of different minimum holes for each electroplating line. Based on the above data, a program was written using Visual Basic. Finally, simulated samples were fabricated, and data after electroplating and etching were collected and statistically analyzed. The experimental results show that:

(1) The etching process capability is stable and can be included in the program database.

(2) The electroplating efficiency data is consistent with the verified samples and can be included in the database.

(3) Data analysis using Minitab software confirmed that the electroplating conditions and auxiliary processes derived from this program can control etching process-related defects within 1.5%, meeting the requirements.

Key Impacts of PCB on PCBA Quality and Control Strategies

PCBA quality depends not only on the manufacturing process, but also, and more importantly, on the quality of the underlying PCB. The following seven core dimensions analyze how the PCB affects PCBA quality and corresponding control methods:

Board Selection: Matching the application scenario is crucial. FR-4 boards are low-cost and have high mechanical strength, suitable for consumer electronics, but lack high-frequency performance. Rogers and other high-frequency materials are suitable for 5G devices, reducing signal loss. Aluminum substrates offer excellent heat dissipation and are commonly used in power modules. Improper selection can lead to mismatched thermal expansion coefficients during soldering, easily causing solder joint cracking. Key control points include precise selection based on product application and controlling substrate thickness tolerances.

Design Specifications: Avoiding inherent defects. The ratio of pads to apertures must be reasonable, and the solder penetration rate must be ≥75%; otherwise, insertion difficulties or insufficient solder penetration may occur. Component layout should allow for heat dissipation space, and large-size PCB designs should include a 2-3mm support strip to prevent deformation. High-frequency signal lines require proper impedance matching; the minimum line width and spacing are recommended to be no less than 0.1mm to reduce electromagnetic interference.

Surface Treatment: Ensures soldering reliability. While tin plating is low-cost, it results in poor flatness and can easily cause component misalignment. Immersion gold plating provides a smooth surface, but the nickel layer thickness must be controlled at 3-5μm to avoid the black pad effect. OSP (Optical Surface Mount) technology is environmentally friendly and compatible with high-density boards, but its 6-month storage period must be strictly controlled. Companies can choose the appropriate process based on product precision requirements and monitor key parameters.

Flatness Control: Prevents component misalignment. PCB moisture and reflow stress can easily cause deformation, leading to component misalignment and cold solder joints. The design employs a symmetrical layout, and during processing, the reflow soldering temperature rise rate is controlled to not exceed 3℃/second. Simultaneously, tooling fixtures are used to balance stress, effectively reducing deformation.

Solder Mask Quality: Preventing Short Circuit Risks. Solder mask window deviation must be controlled within 0.05mm; otherwise, poor pad coverage will occur. The solder mask thickness must be between 10-40μm; too thin and insulation failure is likely, too thick and solder wetting will be affected. Precision equipment is required to control window accuracy and coating thickness during production.

Cleanliness Management: Reducing Hidden Faults. Flux residue, solder dross, and other contaminants can reduce insulation resistance and even cause component corrosion. Low-solids flux with ≤5% solids content is used, production equipment is cleaned regularly, and preheating temperature is controlled between 90-130℃ to reduce residue accumulation.

Hole Wall Quality: Ensuring Signal Connectivity. Hole wall roughness exceeding 25μm can easily lead to uneven copper plating and voids, affecting signal transmission. During the design phase, dense vias should be avoided to prevent thermal stress concentration. During the manufacturing process, drilling accuracy and electroplating processes should be strictly controlled to ensure stable conductivity of the hole walls.
