What is the pcb circuit board process? Ask the technical engineer what to say
This battery, this battery, that battery, unfortunately, has not yet been mass-produced on the road, and there are several experimental bus routes in use.

Circuit board factory teach you how to distinguish PCB circuit board is good or bad?
many times if the site sorting, rectification and other work to do, then some of the existing quality problems will improve a lot.
Factors influencing the quality of pcba process
Many factors affect the quality of PCBA quality, including human, machine, material factors, technological factors, environmental factors, etc. The quality of pcba process is mainly affected by the following conditions.
The knack of making circuit boards quickly
Want to really fast production of high precision, good performance, and can save the cost of PCB circuit board, this is undoubtedly the biggest challenge for circuit design engineers.
Detail electronic processing plant is how to make a circuit board?
At present, the PCBA processing and assembly of circuit boards are basically welded on the printed circuit board by soldering the electronic parts. This welding process can be achieved by SMT or wave soldering.
How to reduce the surface tension and viscosity in PCBA welding
Pay attention to the wiring of signal lines under the magnetic beads, between the pads and those that may come into contact with the magnetic beads. Some magnetic beads conduct electricity quite well and may produce unexpected conductive paths.
How does smt plant control PCBA quality?
Aluminum substrate and glass fiber plate difference and applicationFirst, glass fiber board (FR4, single-sided, double-sided, multi-layer PCB circuit board, impedance board, blind buried hole board), suitable for computer, mobile phone and other electroni
SMT plant to teach you to distinguish simple solder net and red rubber net
Patch processing manufacturers will determine whether to make solder paste steel net or red rubber steel net based on the component design of PCB board. Generally, if there are many plug-ins, wave soldering is required, red rubber net process will be used
What are the main difficulties in making multilayer PCB board
Traditionally, we define PCB boards with more than 4 layers as "multilayer PCB boards", and more than 10 layers as "high multilayer PCB boards".
How to check PCB quality after welding? What are the methods
The optical method uses scanning to find defects in each layer, and the electronic test usually uses a flying probe to check all connections. Electronic tests are more accurate at finding short or open circuits, but optical tests can more easily detect in
What is the principle of rework and repair of pcb board processing?
in fact, no matter how to produce or design, ultimately can not be separated from the consideration of money, so should all the factors into the amount to make the final measurement standard to choose a suitable plate method.
There are four main methods of electroplating in circuit board
Through the above five points of analysis, we should be able to find the cause of short circuit tinning of PCB board after wave soldering.
