How is the circuit board made? What equipment is needed for the production process?

The production process of PCB board can be roughly divided into:

Printed circuit board - inner layer circuit - pressing - drilling - plated through hole (primary copper) - outer layer circuit (secondary copper) - solder resist green paint - text printing - contact processing - forming cutting - final inspection and packaging.

So there are a lot of equipment involved, what equipment does the pcb need? Production and production of pcb circuit boards generally need to be used: lamination machine, exposure machine, etching machine, AOI inspection and repair machine, punching machine, board fusion machine, laminating machine, shooting machine, edge milling machine, drilling machine, sinking machine, etc. Copper wire, electroplating line, green oil grinding line, front and rear processing line, screen printing machine, corresponding equipment for surface treatment, trimming machine, electric measuring machine, warping machine. These things are the main equipment, and there are many auxiliary equipment and instruments.

What auxiliary equipment is needed for PCB manufacturing?

In the PCB manufacturing process, there are many production equipment, including SMT equipment, solder paste printing equipment, reflow soldering, wave soldering and other production equipment. There are also AOI, offline AOI, X-RAY and other testing equipment. In addition to these large-scale production equipment, there are also many auxiliary equipment to complete the PCB manufacturing production.

There are a lot of auxiliary equipment on the production line, let's take a look at it together, shall we? E.g:

1. A smoke purification system used to remove harmful gases such as flux volatiles in the working environment;

2. Refrigerators for storing materials such as solder paste and patch glue;

3. A solder paste mixer used to stir the solder paste and return the solder paste to room temperature through stirring;

4. Solder paste viscosity tester, solder paste thickness tester, dry storage box for storing SMD devices that need moisture-proof storage;

5. An oven used for dehumidification treatment of damp SMD devices;

6. Anti-static facilities and measuring instruments;

7. Sufficient anti-static turnover boxes, logistics trolleys, and feeder racks;

8. If there are jigsaw panels in the product, it should also be equipped with a board cutting machine for cutting PCBs. It is very troublesome to manually count the components and materials of small particles. PCB manufacturers will also purchase material counting machines and other large and small auxiliary production small device.

In addition, the auxiliary equipment and materials of the PCB manufacturing production line should also be configured according to the specific conditions of the product.
