The outline of printed circuit board processing techniques

The people who engaged in printed circuit board processing will be understanding, PCB outline processing is also one of the difficulties of PCB making, most of the PCB is a rectangle shape, but a considerable number of PCB have a special shape.

PCB outline processing methods:

1. Milling outline: the use of CNC milling machines process outline, it should be provied the milling outline data and corresponding positioning holes data, these datas provided by the programmer. As there is not a great distance between the printed circuit boards, generally about 3mm, so generally use 3mm or 2.4mm diameter cutter.

2. Punching outline: the use of punch punching outline, need of the mold and let positioning pin correspond to the positioning hole of the PCB, usually selected 3.0mm hole for positioning the holes.

3. Open “V” groove: the use of “V” groove cutting machine along the PCB design “V” slot cut the boards into several connected parts;

4. Drill outline: the use of drill to drill holes at the edge of the contour.

Normally open “V” groove and drill only for processing aids.

With the development of printed circuit board design, outline processing technology is also developing. Our company also follow up with the development of requirements of PCB technology and production to keep our products with high quality.

FPC&PCB CAM software

 FPC&PCB CAM Software is computer-aided manufacturing technology, for short CAM, is controlled by a computer to complete the production of advanced technology. With the emergence of development of computer technology and laser drawing machine, making the PCB computer-aided manufacturing technology into application. CAM technology enables PCB design into a new level,some functions can not be achieved in the past to implement now. CAM systems are generally able to handle Gerber data, rule out the design in a variety of disabilities that make it easier the design to production, greatly
improving the production quality.

FPC&PCB CAM system’s main functions are as follows:

1, the editing features:

1) Add pads, lines, arcs, characters and other elements.

2) modify the pad, the line size.

3) Move the pads, lines, size and so on.

4) Remove all kinds of graphics, and automatically remove no electrical connection of the pad and via holes.

5) Solder drain line automatic processing.

6) Screen Printing cover pad automatic processing.

2, make-up, rotation and mirroring.

3, adding a variety of positioning holes.

4, generate CNC drilling and milling drill data form the data.

5, the calculation of conductor copper area.

6, other related types of data.
