Half Hole Fr4 2 layer PCB
【Brief】:

The so-called metallized half hole refers to a drilling hole (drill, groove) after being perforated, then two drilling, shape process, and finally retain half of the metallized hole (groove). 

Module PCB is basically designed with half holes, mainly to facilitate welding, module area is small, functional requirements.

 The usual half hole is the design hole on the most edge of the PCB single, and half of the gong is removed in the shape of the gong, leaving only half of the hole on the PCB, commonly known as the half hole.

1.What is Half hole PCB Board?

With the growth of market demand for end applications, the global PCB industry is constantly developing, of which PCB half-hole processing is one of the key development directions. PCB board half holes, also called stamp holes in the PCB industry, can be directly welded with the main side of the hole, which can save connectors and space, and is widely used in signal circuits.

2.What is manfacture proccess?


1. The engineering department shall formulate the MI process according to the technological process

2, the metal half hole is a drilling out (or gong out), after plating, etching before the two drill half holes, must consider the shape of the gong slot will not be exposed to copper, the drill half hole will move to the unit

3, right hole (drill half hole)

(1) After drilling, turn the board over (or mirror) : drill the left hole

(2) The purpose is to reduce the pulling of the drill knife on the copper in the half hole, resulting in the loss of copper in the hole.

4, according to the spacing of the contour line to determine the drill size of the drill half hole.

5, draw solder resistance film, gong vacancy as a file point window increase to 4mil processing.
