Will the design error of screen printing position number affect PCBA patch processing? It can be clearly said that the screen printing position number does not determine whether the final patch is correct.
Suitable PCBA patch processing manufacturers can not only bring high quality costs for enterprises, but also bring cost-effective returns. Therefore, in the selection of PCBA patch processing manufacturers, electronics factories are very careful. So, how
The production qualification of PCBA patch processing plant is reflected in many aspects, such as whether there is ISO9001 quality management system certification, whether there is the United States UL certification, whether there is the European Union RO

Due to the high temperature pyrolysis of the organic matter in the flux, it is difficult for the air bubbles to escape, resulting in the gas being wrapped in the alloy powder. From the process can be seen, organic matter by the heat produced by the main w
Common pads are: 1, square pad, 2, round pad, 3, island pad, 4, polygonal pad, 5, oval pad, 6, open shape pad
The silk screen position number does not determine whether the final patch is correct. Many experienced engineers found that deleting the bit number silk screen printing, PCBA product patch back and no problem. Generally, the machine patch locates the dev
The reasons for white spots in PCBA processing are as follows: 1. The circuit board is under inappropriate thermal stress; 2. 2. Due to the influence of mechanical force, part of the resin is separated from the glass fiber, forming white spots; 3. Some PC
Any non-standard operation in any link will seriously affect the quality of PCBA patch. The quality of PCBA patch can be controlled through the key links of steel mesh making, solder paste control, furnace temperature curve setting and AOI detection.
The basic process composition of SMT patch processing includes: screen printing (or dispensing), mounting (curing), reflow welding, cleaning, detection, repair screen printing
The basic working conditions of PCBA patch after processing are as follows: 1. Working conditions: Temperature: 18℃ to 28℃, humidity: 35% ~ 75%; 2. 2. Operation object: all PCbas; 3. Operator: with certain general SMT and DIP welding status identification
In PCBA manufacturing process, the solder paste printing and the system quality control details of reflux temperature control are the key links in PCBA manufacturing process, which is very necessary for the printing of high-precision PCB with special comp
