How to solve the problem of chip components standing up during SMT assembly?

In the PCBA processing industry, most pcba processing manufacturers will encounter the undesirable phenomenon. During the SMT patch assembly process, one end of the chip component is lifted, causing the component to stand up. This situation often occurs in small-sized chip RC components, especially 0402 chip capacitors. 1. Formation reasons: 1.1. The melting time of the solder paste at both…

Advantages and disadvantages of PCB flying probe testing

After the PCB sample is manufactured, it needs to be tested, and the quality can be guaranteed before it can be delivered to the customer. The PCB Flying Probe Test is one of the more effective test methods. PCB flying probe testing is to check the electrical function of the PCB, using four to eight independently controlled probes that move to the component under test. UUT – Unit Under Test is…

How to distinguish the number of pcb layers?

In the case of single sided, double sided and multilayer PCB using the same board and the same volume, the weight of multilayer PCB is greater than that of double sided pcb, and the weight of double sided pcb is greater than that of single sided pcb. Single sided pcb: that is, only one side of the PCB board has lines (may have holes or no holes), and the other side is covered with substrate or…

Reasons for the displacement of electronic components during SMT assembly

The main purpose of SMT assembly is to accurately place the components on the fixed position of the PCB circuit board. However, some process problems sometimes occur during the SMT assembly process, which affect the assembly quality, such as the displacement of components and the connection of the SMT assembly. Various process problems such as tin and solder leakage. Regardless of the cause, the…

The concept and process flow of PCB bonding

PCB Bonding is a method of wire bonding in the chip production process. It is generally used to connect the internal circuit of the chip with gold wire or aluminum wire and the package pins or circuit board gold-plated copper foil before packaging. Ultrasonic waves from an ultrasonic generator (generally 40-140KHz), the high-frequency vibration is generated by the transducer, and transmitted to…
