How long is the PCBA processing quotation cycle?
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.
Do you know the requirements for PCBA processing
The company gives full play to its competitive advantages in scale procurement and quality control, and has signed long-term cooperation agreements with many electronic component manufacturers at home and abroad and around the world to ensure the quality
Do you know the various processes in PCBA processing?
Long-term maintenance of IC, resistors, capacitors, inductors, audiodes and other components procurement advantages, can greatly save customers' inventory costs, improve production turnover efficiency, save time. Currently for the United States
Soldering requirements for PCB circuit boards in PCB assembly
PCBA welding processing, there are usually many requirements for the PCBA board, and the requirements must be met in order to weld.Then why does the welding process need so many requirements for the PCBA board?
How to improve the pass rate of SMT patch processing?
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.
SMT patch processing requirements for flux
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.
The role of PCB reinforcement in PCBA processing
The company gives full play to its competitive advantages in scale procurement and quality control, and has signed long-term cooperation agreements with many electronic component manufacturers at home and abroad and around the world to ensure the quality
The PCBA processing, automatic optical inspection is usually
In PCBA processing, automatic optical inspection is usually set at the last step of the SMT production line, and it is necessary to detect the defects of the product after the completion of the SMT processing process.
The meaning of silk screen letters on the PCB board
R107, C118, Q102, D202 and other numbers are often seen on the PCB board. In general, the first letter identifies the device category, such as R for resistor, C for capacitor, D for diode, Q for transistor, etc.
What should I do when I encounter bad welded components in PCBA processing services?
Poorly welded electronic components. In the face of this situation, we generally remove poorly welded electronic components without damaging the PCB board.
PCBA processing electrostatic protection measures and precautions
The PCBA board damaged by static electricity is difficult to gradually investigate during functional testing. What is more fatal is that some PCBA boards function normally during testing
