Description

Dacron strip brush in PCB processing and manufacturing of the wide wireframe production and manufacturing industry, such as graphic boundaries/line distance > 200um(8 m IL), copper mooring thickness ≥35um is very ideal selection, sometimes can also open to > 150um(=6mil). Because of its high rebound force, polyester strip brush will not damage the brush roller in the case of PCB board warping or twist drill broken, and the seamless roller brush will not cause the brush roller imbalance and damage to the PCB circuit board and brush roller in the case of operator mistakes such as forgetting to cool the circulating water. The following enterprises to introduce the fine hair roller brush polyester strip brush in PCB processing and manufacturing in detail.


1. Deburring process after drilling. When the burr exceeds 75um, the following components are used: 180# silicon carbide and 240# silicon carbide.


2. Deburring process after drilling. When the burr exceeds 50um, the following components are used: 240# silicon carbide and 320# silicon carbide.


3. Deburring process after drilling. When the burr is lower than 50um, the following components are used: 320# silicon carbide and 320# silicon carbide.
