Mixing process is in the PCB board A side has a number of IC components, and inserted with through hole components, on the other side of the PCB (B side) and there are many patch resistance capacitance electrical parts, sometimes IC, often called "mi...
The reasons for the need for post-welding processing are as follows: 1, the components are not resistant to high temperature, 2, the components are too high, 3, there are a small number of plug-ins in the side of the wave crest, 4, the components plug-in
In PCBA processing, there are several process points in the whole process of rework and reflow: 1. Repair reflow welding curve should be close to the original welding curve. 2. In the reflux process, the heating temperature and time of each area should be
The quality control of the whole pcba process is very important. 1.PCB circuit board manufacturing; 2.PCBA incoming components procurement and inspection; 3.SMT patch processing; 4. Plug-in processing, 5. Program burning, 6.PCBA board test
What are SMT patch, PCB circuit board, PCBA processing and DIP plug-in respectively? First, SMT is one of the basic components of electronic components, which is called surface assembly technology; second, PCB is the most important component of electronic
5 PCBA processing automation production of PCB size, shape, transmission edge, positioning hole, positioning symbol requirements.
In the process of electronic machining, the smaller the Angle of the scraper affects the vertical force of the solder paste, the greater the vertical component of the force.
Circuit is easy to be damaged in overvoltage, overcurrent, surge, etc. With the development of technology, PCB products are increasingly diversified and complicated, and circuit protection becomes particularly important.
Circuit boards must use the thinnest coating material to provide maximum protection in order to minimize heat retention, additional weight gain and various other problems.
SMT patch proofing and mounting on the space the size of the pinky finger means higher reliability and mounting accuracy, and two great progress can be summarized: first, the number of chip welding pins is reduced, and second, the welding volume is smalle
The quality of component package will directly affect the performance of chip itself and PCB design and manufacture connected with it.
By shortening construction time and compressing work-in-process retention.Difficulty is the ladder of success, the success of the process is reasonable, reasonable, reasonable.
