Yes, we accept T/T, West Union, Money Gram, L/C, and PayPal for sample transactions. For more details on payments, please consult our sales team.
2.What kinds of inspections are carried out on PCBs?
We perform various inspections such as AOI, x-ray, in-circuit testing, functional testing, and flying probe testing to ensure product quality.
3.What is the purpose of a solder mask on PCB?
Solder mask is a thin polymer layer on the PCB to protect the surface of the circuit board. The main purpose is to prevent solder bridges and oxidation of copper traces.
4.Why choose the black solder mask for a flexible PCB prototype?
Black solder mask offers some advantages over green ones, like enhanced heat dissipation, better aesthetic appeal, reduced light reflection, improved contrast for inspection, etc.
5.What are the typical applications of black solder mask flexible PCB prototype?
Black solder mask flexible PCB prototypes are used in applications that require aesthetics, thermal management, and reduced light reflection, such as high-end consumer electronics (wearable devices), flexible LED lighting, etc.
