Benefits of PCB board

1, convenient production

Some PCBS are too small to meet the requirements of SMT fixtures, so several PCBS must be put together before SMT production can be carried out.

2, cost savings

Some circuit boards are special in shape, so the area of PCB substrate can be used more effectively through assembling, reducing waste and saving cost.

PCB board notes

1. Pay attention to leaving edges and slotting when assembling PCB.

The edge is left in order to have a fixed place when welding plug-ins or patches later, and the slot is to separate the PCB board. The process requirements of the edge are generally 2-4mm, and the components should be placed on the PCB board according to the maximum width. Slotting is in the forbidden wiring layer, or the material layer, the specific with PCB manufacturer agreed, processing, designers can mark. PCB board is to facilitate production, improve work efficiency, you can choose.

2, V-groove and slotting are a way of milling appearance.

It is easy to separate multiple boards to avoid damage to the boards during separation. Depending on the shape of the single type you are crafting, the V-cut needs to go straight and is not suitable for four boards of different sizes.

3. Collage requirements

Generally, there are no more than 4 kinds of plates. The layer number, copper thickness and surface process requirements of each plate are the same. In addition, we will negotiate with the engineer of the manufacturer to reach the most reasonable plate-making scheme.

Jigsaw is to save cost. If the production process is complex and the batch is large, it is suggested to produce the jigsaw separately, and the scrap rate varies from 10% to 20%.
