Quality control is very important for patch plug-in processing. Only through effective quality control can we ensure the processing quality of patch plug-in, so as to obtain the best processing effect
What are the advantages of SMT plant? Some very precise circuit board machining can be done by mounting miniature components on the circuit board and connecting components and circuits on the circuit board
SMT plant features: 1, rich devices, 2, efficient manufacturing process, 3, high product accuracy, 4, product environmental resistance, 5, cost-effective
Specifications for PCB storage and inspection in SMT factories: 1. PCB inspection standards and inspection contents; 2. Storage requirements; 3
SMT processing materials on the PCBA welding quality of the impact of the following: 1, the impact of components, 2, PCB, 3, the impact of solder paste
How to select high quality reflow soldering in PCBA processing plant: 1. Look at the heating method of reflow welding; 2. Look at the actual temperature difference of reflow welding; 3
pcba aging test standards: 1, low temperature work, 2, high temperature work, 3, high temperature and high humidity work
Key points of solder paste printing technology: 1, the Angle of the printing press scraper and steel mesh: 2, scraper pressure: 3, scraper speed, 4, printing gap: 5, release speed
Analysis of the causes of holes (bubbles) in solder joints in PCBA patch processing: 1, the influence of flux activity, 2, related to the oxidation degree of PCB pad, 3, the influence of solvent boiling point, 4, related to the welding time, 5, the solder
a large number of pre-test printing solder paste production several pieces to determine no solder problems before continuing to production.
Pin tin absorption can also be reduced by a flux with a slower wetting rate and a higher active temperature, or by a solder paste with different proportions of Sn/Pb to block melting.
In the era of industrialization surplus, circuit board manufacturers in particular, choose a suitable circuit board manufacturers is very important!
