About Metallized Half Hole PCB

The metallized half hole is a half hole at the edge of the plate and is electroplated. Metallized semi-holes are mainly used for the direct connection between plates. They are mainly used to weld together two printed circuit boards with circuit design technology. The whole system takes up much less space than a PCB system using a row pin connector.

Design parameters of half hole PCB

How are metallized half hole PCB made?

First, electroplated through holes are made on the edge of PCs or set (smaller unit in production board PNL), and then half of electroplated through-hole Gong is removed by using gong machine (milling machine), and the remaining half is half hole. Since copper is difficult to process and is likely to cause bit breakage, special gongs are required and higher speed is set to make the surface of hole wall and edge smoother.

Each half hole is then inspected by the semi-finished product inspection station. The minimum diameter of the half holes that can be manufactured by the confluence circuit is 0.5 mm, and the half holes should be at least 0.5 mm apart.
If you need to make a smaller half hole diameter, please contact our customer service personnel to communicate the feasibility plan. When placing a purchase order for a half hole plate to Huihe circuit, please communicate the details of the half hole plate with the technical engineer of Huihe circuit to ensure that you can obtain a cost-effective manufacturing solution.

How to identify a half hole in your design file ?

Half hole is designed because of the structure of the device and circuit board plug-in A single or whole rowof device holes are directly added to the outline of the metalized half hole to ensure that half of the deviceholes are in the board and half are out of the board . The Gerber file should contain the following:

01

Line layer(GTL and GBL)

Half hole brazing pads are located at top and bottom

02

Weld barer layer(GTS and GBS)

Weld barnier opening at half hole position

03

Hole layer (TXT/DRL)

The hole location of each half hole

04

Mechanical/profile layer(GMU/GKO)

The profile should be centered through each half hole
