The production time of SMT patches and DIP plug-ins is relatively short, but also depends on the difficulty of the process and the adequacy of factory orders. The normal lead time for proofing is about 1-3 days. Normal delivery time is about 5-7 days.
SMT chip processing has an important indicator for processing quality evaluation, that is, the straight-through rate. In the patch processing. SMT process pass rate refers to the proportion of one-time qualification from production to the last process.
In the welding process of SMT patch processing, the substance that can purify the welding metal and welding surface and help welding is called flux, referred to as flux.
Shenzhen circuit board assembly and processing manufacturers, providing one-stop services from upstream electronic component procurement to PCB production and processing, SMT patch, DIP plug-in, PCBA testing, finished product assembly and so on.
Since the BOM list provided by the customer is not perfect, the general SMT patch processing plant needs to be converted into the form of internal company files for issuance
There are many SMT processing modes, different processing cooperation modes of the process is different, the corresponding customer needs to prepare things are not the same.
Our company has signed long-term cooperation agreements with many electronic component manufacturers at home and abroad to ensure the quality of products.
We have competitive advantages in scale procurement and quality control, and have signed long-term cooperation agreements with many electronic component manufacturers to ensure quality.
Pay attention to the moisture-proof treatment of BGA, and pay attention to details during installation and soldering.
SMT welding has a close relationship with all aspects of the entire assembly process, and once welding problems occur, product quality will be affected and loss will be caused.
The high quality requirements of SMT chip processing require us to apply a clear work responsibility system, such as SMT chip processing related positions operators need to conduct professional training, and implement the first piece inspection
The steel mesh is originally made of wire mesh, so it is called the mesh board. At first it was nylon (polyester) mesh, and later due to durability, barbed wire appeared. Copper wire mesh, and finally stainless steel mesh. But no matter what the material
