Vacuum Hole Plugging Machine Application: Resin Filling Microvia For Hdi Circuit

This machine is a vacuum selective hole filling system, which is suitable for selective hole filling technology in vacuum state. There will be no air bubbles when filling through holes and laser holes.
There are many through holes and lines on the circuit board. The main function of these through holes and lines is to insert accessories and conduct current. After the PCB board is filled with this equipment, the ink is dried and hardened in an oven, which can protect the surface of the circuit board and the inside of the through hole, avoiding oxidation or scratching of the circuit, and the liquid will not remain inside the through hole, improving the life of the circuit .
This Vacuum plugging Machine fills the holes in a close to vacuum state, so the ink is not easy to produce small air bubbles, which can effectively reduce the bad problems caused by air bubbles on the PCB board.
