Can SMT technology speed up PCB production?
SMT can greatly reduce production time. Moreover, SMT components can be placed in the thousands per hour, compared to less than a thousand for through-hole installations.

PCBA in the manufacturing need to consider the issues :1, automatic production line veneer transmission and positioning elements design,2, PCBA assembly process design,3, component layout design,4, assembly process design
The warping of PCB circuit boards has great influence on the production of printed PCB circuit boards, and warping is one of the important problems in the production process of PCB circuit boards. Bent, component foot is difficult to clean.
PC8 production is not difficult, the difficulty lies in the production of fault troubleshooting. Whether it is an individual hobbyist or an industry engineer, it is quite troublesome to encounter problems when debugging PCB circuit boards.
In the PCB design concept should be reduced as much as possible through the hole. If the number of parallel lines in the same direction is large and dense, they will be joined together during welding.
Ink in the production to protect the role of copper foil, so that the copper skin is not exposed to the outside, will affect the later process, sensitive ink, carbon oil, silver oil, and carbon oil and silver oil have electrical conductivity.
In fact, printed PCB circuit boards used in electronic equipment are different, and printed PCB circuit boards are classified differently according to different specifications.
One of the causes of PCB warping is that the substrate used may warpage, but in the process of PCB processing, due to thermal stress, chemical factors, and improper production process will also cause PCB warpage.
The automotive PCB market is benefiting from the increasing electronization of vehicles as consumers demand more functionality and safety.
Width and spacing of printed wire are important design parameters, which affect not only the electrical performance and electromagnetic compatibility of PCB board, but also the manufacturability and reliability of PCB board.
What do PCB copying boards need to provide: Usually, simple single and double panel copying boards only need to provide one set of samples. If it is multi-layer board, it is better to provide two sets of exactly the same samples, which is convenient for l
PCBA processing wave welding notes :PCBA after wave welding, cleaning board, storage and maintenance may be white around the pad. The white stuff is mostly residue
