PCB PTH Line (Plated-Through-Holes)

Plated Through Hole
 Printed circuit board hole metallization technology is one of the keys to the printed circuit board manufacturing technology.
Plated Through holes is plating a thin copper layer on the inner wall of the hole between the top and bottom walls, to make the top and bottom of the printed circuit board holes connected to each other.

Processing
 Alkaline Degreasing → ​​two or three counter-current rinsing → Coarsening (microetch) → two counter-current rinsing → ​​Pre dip → activation → two counter-current rinsing → two counter-current rinsing → PTH → two counter-current rinsing → ​​Baptist Acid
