TFA Allspark Human twist where Megatron gets pregnant instead of the reader bc the Allspark has a sense of humor
He is humiliated beyond belief but unable to abort that thang because it might represent the dawn of a new age for Cybertronian kind
On May 16, leaders from Shaoyang University — the alma mater of our CEO, Frank — visited STHL for guidance and exchange.
It was more than just an industry-academia meeting. It was a moment to look back at where it all started.
We shared with our honored guests how STHL has grown, our production capabilities, and our journey in the PCBA industry.
We are truly grateful for their encouragement and professional guidance, and for the education that shaped our foundation. No matter how far we go, we never forget where we began.
Unseen Solder Joints, See Them Clearly with X-Ray
Solder balls on the bottom of BGAs, solder run-through on the sides of QFNs, tiny voids and cracks—these details invisible to the naked eye are revealed one by one by STHL using X-Ray.
Not every board needs it, but when it does, it never overlooks any potential problems.
STHL Workshop Daily Life | Every Moment Adds to Reliability
This is our workshop, at its most authentic.
Machines run non-stop, workers are focused and organized, and boards flow silently between production lines. —Every position, in its own way, is writing a footnote to today's quality commitment.
Moments Captured by the Camera Today
Preparation for surface mount line changeover, materials are being neatly shelved.
Colleagues are checking data at the first article inspection machine.
In the repair area, details are being re-examined and reinforced.
From the SMT workshop to the manual DIP insertion, the camera pans across every corner of the factory, recording not only the operation of the equipment, but also our daily commitment to "reliability."
We believe: True manufacturing lies in every meticulously handled detail.
From the starting point to the finish line of a circuit board, our unwavering respect for quality remains constant.
Automatic Optical Inspection makes PCBA quality control simple and reliable.
Cameras take pictures of each board.
⚖️ The system compares them with a standard image.
❌ If something is missing, misplaced, or poorly soldered, AOI spots it instantly.
In STHL's SMT workshop, reflow soldering is not just a process step, but a core technology determining soldering reliability. We use precise temperature control to ensure every solder joint reaches a perfect state.
2 x 10-zone reflow ovens + 1 x 8-zone reflow oven
Supports soldering needs from simple single-sided boards to complex HDI boards
Optional nitrogen process, oxygen concentration < 1000ppm
Oxidation rate reduced by 90%, resulting in bright and full solder joints
Stable temperature rise, safe solvent evaporation
Fluoride activation, oxide removal
Precise temperature control, achieving perfect eutectic bonding
Optimized solidification structure, improved solder joint strength
► Lateral Temperature Difference < ± 2℃
► Supports lead-free/lead-containing process switching
► Real-time temperature profile monitoring and traceability
BGA void rate controlled below 8%
Soldering defect rate reduced by 35%
Supports automotive electronics-grade reliability requirements
We ensure that the temperature profile of every board is a testament to quality
In STHL's SMT workshop, the loading area is the core hub ensuring efficient production. The neatly arranged feeders here are not only material carriers but also our precision arsenal for rapid line changeovers.
Intelligent Feeder Area Working Logic
✅ Pre-loading System
The trays of materials for projects about to go into production are pre-loaded into the feeders.
A unique project ID tag is generated, achieving precise material matching.
✅ Rapid Line Changeover Mechanism
The entire feeder rack is replaced directly during production line changes.
STHL Feeder Area Core Values
► Increased Capacity: Utilizing production gaps for material preparation, increasing equipment uptime by 35%.
► Zero Error Rate: Eliminating the risk of incorrect materials through dual barcode verification.
► Flexible Response: Supporting parallel material preparation for up to three urgent order insertion projects.
We make production flow as smooth as a symphony.
At STHL, the precise positioning of each feeder is a solemn commitment to customer delivery deadlines.
