The reason for the appearance of false welding/false welding; 1, solder pad and component pin oxidation, 2, less tin, 3, temperature is too high or too low, 4, low melting point of solder paste, 5, solder paste quality problem,
In PCB production process, in addition to pressing, there are several high temperature treatment processes, such as welding resistance, characterization and hot air smoothing.
Basically, V-Cut is the culprit of damaging the structure of the board, because V-Cut is in the original a large sheet of the board to cut out grooves, so the V-Cut place is prone to deformation.
When PCB is assembled, do not apply any solder to the top or bottom pad. Use screws with built-in washers to achieve tight contact between the PCB and the metal case/shield or ground surface bracket.
Printed circuit boards using Bluetooth technology may experience interference, data loss, and poor signal integrity if certain precautions are not taken.
Surface treatment is very necessary for PCB circuit processing. It not only provides a smooth weldable surface for component welding, but also provides protection for the copper conductor of the PCB.
it is critical that your PCB components be accurate and functional. Therefore, dealing with reliable PCB component manufacturers and service providers is critical.
The following article illustrates the different materials used to manufacture PCBS for networking and communication applications. Again, various useful features and characteristics of these materials are discussed in the post. Read on to learn more.
There are many issues to consider in RF design, as the correct design choice depends largely on the primary operating frequency and whether the RF board is really a mixed signal board.
SMT patch processing PCBA overhaul includes what aspects: ① Check the electronic devices, each spot welding electronic devices are not wrong version, leakage, reverse problem exists, ② spot welding welding is not smooth, there is no abnormality, ③ query d
This streamlined production solution helps eliminate quality control issues that arise when boards are switched between different processes.
All of these tools are important when creating various layers and using different components to make printed circuit boards for complex applications.
