Questions & Answers
1. Does MOKOPCB support mass production?
Yes, we have the capacity to handle small to high-volume PCB production with automated assembly lines.
2. What’s the minimum PCB size you can make?
The minimum size we can make is 10*10mm.
3. What is your payment terms?
T/T, Paypal, Western union, L/C ,ESROW
4. How to prevent trace breaks in a flexible LED ring PCB?
We optimize trace layout to avoid bends, use optimal flexible materials like polyimide, and maintain proper bend radius to prevent trace breaks. Our workers will make tests with bend cycles and inspect for microcracks.
5. How durable is the polyimide LED ring?
The polyimide LED ring is very durable if designed correctly. It remains static if the bend radius exceeds 6 times of the PCB thickness, which can last for over 10 years. The occasional flexing Polyimide LED PCB can be used for 5-10 years with hundreds of bends. The dynamic flexing LED PCB can bend forever.
6. What’s the minimum thickness of polyimide PCB that you can make?
The minimum polyimide thickness is 0.1mm. 0.3mm for 4-layer and 0.8mm for 10-layer.
7. How to avoid overheating in flexible LED ring PCB?
To avoid overheating, we use thicker copper and drill thermal vias and exposed pads to dissipate heat. Besides, we optimize power efficiency with higher efficient LEDs and proper current limiting to avoid producing excessive heat.
8. How to solder LEDs on a polyimide PCB without damaging it?
Soldering LEDs onto polyimide PCB requires low heat and fast soldering to avoid damaging heat-sensitive polyimide. We utilize fin-tip iron, flux, and pre-tinned pads to get clean joints, or choose low-temperature solder for safety.
