Today author from QiHe smt pick and place machine smt equipment manufacturers sharing you with Problems that are prone to occur in the process of PCB plate making<\/p>\n\n\n\n

When we design on PCB design software,
Often due to the seemingly connected parts (electrical performance) on the plane but actually not connected,
So when we start plate making according to the design document,
Order of operations is very important.
Today we go through the following three tricks,
Focus on solving the problems that are prone to occur in the process of PCB plate making.<\/p>\n\n\n\n

A making a physical frame<\/p>\n\n\n\n

Making a closed physical frame on the original board is a constraint effect on the layout and wiring of later components.
After a reasonable physical frame setting,
The soldering of components one by one and the accuracy of wiring can be more standardized.
But pay special attention to,
Some boards or corners with curved edges,
The physical border should also be set in an arc shape,
The first precaution is to prevent sharp corners from scratching workers,
The second stress relief effect ensures safety during transport.<\/p>\n\n\n\n

B. Introduction of components and networks<\/p>\n\n\n\n

It should be easy to draw components and nets into the drawn border,
But there is often a problem here,
Be sure to carefully solve the errors one by one according to the prompts,
Otherwise, it will take more effort later on.
The problems here are generally the following:<\/p>\n\n\n\n

The packaging method of the component cannot be found,
component network issues,
There are unused components or pins,
Control hints that these problems can be solved quickly.<\/p>\n\n\n\n

C\uff0e Layout normalization of components<\/p>\n\n\n\n

(1) Placement order
Experienced installers will first place components with a fixed orientation related to the structure,
Such as power sockets, indicator lights, switches, connectors and the like.
Then it is locked by software,
Make sure that the components with fixed orientation are moved or affected when other components are placed later.<\/p>\n\n\n\n

complex board,
We can divide according to the placement order,
Do it several times.<\/p>\n\n\n\n

(2) Pay attention to the influence of layout on heat dissipation
Component layout should also pay special attention to heat dissipation.
Regarding high-power circuits,
Those heating elements such as power tubes and transformers should be placed as far as possible in a scattered layout.
for heat release,
Don’t concentrate in one place,
Also don’t put the high capacitance too close to avoid premature aging of the electrolyte.<\/p>\n\n\n\n

Through the above three points, I hope to help the engineers of PCB production.<\/p>\n\n\n\n
