Vacuum Hole Plugging Machine

Backed by rich industry experiences, we are leading Exporter, Manufacturer & Supplier of Vacuum Hole Plugging Machine in Guangzhou, Guangdong, China.
Usagei
Specially designed machine for resin plugging process for PCB industry, recommended to use in PCB blind holes plugging, big/small hole plugging, small hole in thick panel plugging and selective plugging and son on.
The VPM fills holes under vacuum environment, so it can prevent the tiny bubbles in the paste when filling the holes. It also can effectively reduce the air bubble produced.

1.Equipment principles and advantages
1.1 Principle as shown in the figure belowi
i Two chambers design. It can be connected and isolated between the big and small chambers.
i To fill the hole in big vacuum chamber, to load and unload PCB on the small vacuum chamber.
i When load and unload PCB, we only need open the small vacuum chamber, at the same time, it is isolated between the two chambers. Which can improve the hole plugging efficiency.
i The equipment can be used to selective hole plugging under vacuum. Plug hole aspect ratio: Through hole 30:1, Blind hole:5:1. It also can plug the back-drilling hole.
