Product Description

18L/transformr PCB/3OZ/high TG/half hole plated/5OZ/Burid hole

 

Winding PCB is normally applied to transformer product and adapter. It is widely applied the consumer,communication, automotive industry.


1. They required high technology requriement such as:


1) Material:high TG material: Critical RC% and copper foil choose.
2)Copper thickness: heavy copper 3OZ to 10OZ,
3) Special technology burid holes, depth drilling, PI materail used etc.
4)) Resin plugging+hole plated over,
5)Special soldermask to be taken high voltage.


2. The PCB needs to be tested as following:


1) Resistance test, inductance test, high voltage test and even capacitance test, Q value etc.

2) Reliability test: CAF test, solderability test,thermal shock test, temperature cycling test etc.

 

How to know the dielectric thickness can be withstand voltage value? Is the same voltage level with different kind materails?
