There are four main methods of welding: Surface mount reflow soldering (SMT) Full board wave soldering Selective soldering manual welding Each method leaves a different degree of risk, resulting in the presence of flux residues, which may l

1 Introduction In the circuit board assembly, solder paste is printed on the pads of the circuit board first, then various electronic components are mounted, and finally passed through a reflow furnace. After the solder balls in the solder

The development of modern science and technology has led to the miniaturization of electronic components and the large-scale application of SMT technology and equipment in electronic products. SMT manufacturing equipment has the characteris

The appearance and trend of electronic products, the volume of products is becoming smaller and smaller, the function is becoming more and more diversified, the components are becoming more and more sophisticated, the stability of the produ

Basic requirements for anti-static in PCBA electronics factories: 1. The basic principles of electrostatic protection a. Inhibit the accumulation of static charge; b. Eliminate the static charge that has been generated quickly, safely and e

SMT solder paste printing stencil (stencil) is also called SMT stencil, SMT screen, SMT stencil. It is used to quantify solder paste or patch red glue, and is the key to ensuring the quality of printed solder paste/ patch red glue Tooling.

Sometimes the device is dying, sometimes it is stressful but not obvious. The end of life of a device is a cumulative decay effect originating from physical or chemical changes. Everyone knows that electrolytic capacitors and certain types
