SMT placement sale _ Ren Jie Electronics (certified) _SMT patch

 Purpose SMT adhesive patch to prevent components falling ① wave (wave soldering process). When using wave soldering, the PCB solder tank to prevent components falling through, while the component is fixed to the printed circuit board. ② reflow components off to prevent the other side (double-sided reflow process). Double-sided reflow process in Shandong SMT patch, in order to prevent the surface of the welded large devices that heat because the solder melts off, to make there SMT plastic patch. ③ prevent displacement and vertical components of the (reflow process, the pre-coating process). For reflow soldering processes of displacement and vertical sheet and pre-coating process in time to prevent the placement. ④ mark (wave soldering, reflow soldering, the pre-coat). In addition, PCB and component batch change, marked by patches of plastic. SMT surface mount technology, the English call 'SurfaceMountTechnology', referred to as the SMT, which is affixed to a surface mount components, soldered to the printed circuit board surface mounted circuit linking techniques specified location. Specifically, the first in the PCB circuit plate coated solder SMT chip manufacturers, and then the surface mount components accurately onto the coated solder pads, a printed circuit board by heating until the solder cream melting, after cooling to achieve the interconnection between elements with the PCB. 1980s, SMT production technologies are maturing Weifang SMT chip sell for surface mount technology components for mass production, price declines, and good technical performance, low-cost devices have been available with SMT electronic assembly Products with small size, good performance, full-featured, low price advantage, so the SMT as a new generation of electronic assembly technology, is widely used in aviation, aerospace, communications, computer, medical electronics, automotive, office automation, household appliances Electronics equipment linked in various fields. smt chip processing advantages: high packing density, electronic products small size, light weight about SMT chip, chip component size and weight of only the traditional instrumentation components 1/10, after the general use of SMT, electronic products smaller in size 40 % to 60% weight reduction of 60% to 80%. High reliability, strong anti-vibration capability. Solder joint defect rate. Good high-frequency characteristics. Reduce electromagnetic and radio frequency interference. Easy to automate, improve production efficiency. Cost reduction of 30% to 50%. Saving materials, energy, equipment, manpower and time.
