PCBA processing plant production efficiency increase 10 magic weapon
By shortening construction time and compressing work-in-process retention.Difficulty is the ladder of success, the success of the process is reasonable, reasonable, reasonable.
How do electronic engineers place PCB components?
The fact that there are few restrictions on where components can be placed and no "infallible" rules doesn't mean you can do whatever you want.
PCBA electronic engineer notice 10 kinds of free easy to use circuit design software!
Engineering software and online resources tend to be expensive, but can be very beneficial for professionals, students, and hobbyists.
Is there poison in the soldering iron solder in PCBA processing?
Normally speaking, if the protection and raw material procurement in accordance with national standards, solder will not cause significant harm. Now it's basically lead-free products.
What are the differences between PCB layers?
In the design of PCB, I found that many people do not understand the layers of PCB, each layer has the characteristics of each layer, function.
How does a PCBA electronics engineer repair a non-drawing circuit board?
When looking for faulty capacitors, it is important to check the capacitors close to the heat source, such as the capacitors near the heat sink and high-power components. The closer to the capacitors, the greater the possibility of damage.
Must know PCB processing plant 8 kinds of detection technology
With the development of miniaturization of electronic products and high-density assembly of circuit board components, SMT production and testing have brought great challenges.
Hard to design PCB board, but do not let the hole destroyed!
Through hole is one of the important components of multi-layer PCB. From the perspective of function, through hole can be divided into two categories: one is the electrical connection between each layer; The second is the device fixing or positioning.
Why do PCB boards warp? What is the harm after deformation?
On the automatic surface mounting line, if the PCB is not smooth, it will cause inaccurate positioning, components cannot be inserted or affixed to the holes of the board and the surface mounting pad, and even crash the automatic inserting machine.
Deformation caused in the process of PCB board processing
PCB deformation causes can be divided into thermal stress and mechanical stress. The thermal stress is mainly produced in the process of pressing, and the mechanical stress is mainly produced in the process of stacking, handling and baking.
PCB design skills of switching power supply
In any switching power supply design, the physical design of the PCB board is the last link. If the design method is not correct, the PCB may radiate excessive electromagnetic interference, causing the power supply to work unstable.
