We are confidents to provide with CUSTOMIZED high quality Epoxy glass fiber Fr4/g10 products by our professional manufacturing team,  manufacturing lines and experienced CNC router operators who have been engaged in this industry for more than 10 years.



1. Spacer for choke and inductor coil


The epoxy glass fiber sheet serves as an insulation spacer for the upper choke.


The common mode inductance is divided into high voltage AC mode and output DC mode. The voltage between the two copper wires determines whether to use the spacer. If the lead string is added and the casing voltage is not high enough, the spacer shall not be added. But considering the consistency, it is more appropriate to have an insulation spacer in bulk production.  




2. Baseboard for Transformer Bobbin


The functions of transformer’s bobbin are as follows:

(1)To provide enough space for twining copper wires

(2)To fix the magnetic core of the transformer

(3)To support wires twining of the transformer by its wire channels

(4)To serve as a conductive component after it is soldered with tin and connected to PCB sheet

(5)To decide the direction of the transformer by its chamfer



3. Used as washers


(1) Sealing

(2) Increasing friction 

(3) Reducing pressure

(4) Bearing high temperature
