As the saying goes: details determine success or failure, a nail will damage a horse, and a horse will lose its place. As one of the details of the circuit board, PCBA is its important component, which is related to its quality and even determines the "fate" of many products. It can be seen that PCBA processing is not a simple process, and various process documents will be used.

So what exactly are there? Let’s take a look with the editor below, it is pure dry goods sharing, hurry up and collect it!

1. Block diagram

I believe that many engineers and friends know that a good block diagram can let their customers know the intention and design ideas of the designer. It is a kind of diagram with annotations, which outlines the basic composition, interrelationship and main characteristics of electronic products. The block diagram The "box" represents a functional block, and the "wire" represents the routing or sequence of signals through the circuit.

2. Circuit schematic

This is actually very easy to understand. It is a drawing for the arrangement of various components in a product. Generally speaking, it does not consider the actual position of the components. Of course, it does not represent the shape and size of each component. The circuit schematic diagram is in the circuit block diagram. It is drawn on the basis of the design, wiring and product performance analysis and maintenance. It should be noted that its requirements are relatively strict, whether it is layout or aesthetics, etc. There are certain requirements, and there are certain requirements between components in the circuit diagram. Wires represent wires, and the junctions of two or more wires are marked with solid dots.

PCB Assembly

3. List of supporting materials

In short, a list of requirements.

4. Parts schematic

It should be noted that there are two parts in this part: one is the printed circuit board assembly drawing and the other is the schematic diagram of the chassis panel. For complex electronic products, the process file also includes wiring diagrams and wiring tables.

5. Drawing

For the connection of uncomplicated electronic products, there is no need to tie wires, but for complex products, because there are many connecting wires, the connection is complicated, it is difficult to find or affects the appearance, and it is generally required to draw wires and tie the wires.

The above content about the process file PCBA processing needs to be used, and it is also very important to let the user know the assembly position and overall appearance of the parts.
