Electronic components procurement knowledge and processGenerally speaking, supplier development includes: analysis of supply market competition, finding qualified suppliers, evaluation of potential suppliers, inquiry and quotation, negotiation of contract
Electronic Components Procurement SummaryThe premise of purchasing is to understand and be familiar with what you purchase, that is, to learn the relevant knowledge of electronic components. Then comes the needs assessment, determining the type and quanti
The semi-molten solder paste is placed on the circuit board by the steel mold, and then the SMD components are pasted on it, and it is welded on the circuit board by reflow welding
SMT patch process: 1, cleaning, 2, pre-welding: 3, patch: 4, welding: 5, detection: 6, assembly
Check the buffering action of the suction nozzle fixture of the parts of the patch machine on time. If the buffering action is not smooth, it is recommended to apply a thin layer of lubricant. If the fixture is loose, tighten the moving lens to clean the
PCB has become the most important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment.
That's all we have manufacturing capacity for, and when 5G starts in earnest, it will put pressure on those parts markets.
The size of electronic devices is also getting smaller, which requires that the heat dissipation device itself should have certain heat dissipation conditions, and the heat dissipation device itself should also have certain heat dissipation conditions.
The lead inductance of patch resistors and capacitors is greatly reduced, which has great advantages in high frequency circuits. The disadvantage of surface mounted components is that they are not easily welded by hand.
In the printing industry, photo platemaking is often used to produce pictures on paper. That is, by taking photos, the picture of the bottom plate, etched on the copper plate or zinc plate, with this copper plate or zinc plate, you can print a lot of pict
The main heat dissipation methods of electronic components include natural heat dissipation or cooling, forced heat dissipation or cooling, liquid heat dissipation, cooling of heat dissipation or cooling, energy channeling in heat dissipation or cooling.
Although the number of electronic components of printed circuit board is large, but its failure is regular to follow. Electronic components distribution order is to help customers professional, efficient, fast, high quality to solve the problem of multi-c
