SMT is the abbreviation for Surface Mounted Technology, the most popular Technology and process in the electronic assembly industry.Electronic circuit Surface Mount Technology (SMT) is called Surface Mount or Surface Mount Technology.It is a kind of Circuit assembly technology that installs leadless or short lead surface assembly components (SMC/SMD in Chinese) on the surface of Printed Circuit Board (PCB) or other substrate surface, and then welds and assembles by means of reflow welding or dip welding.In general, the electronic products we use are made of PCB plus various capacitors, resistors and other electronic components according to the circuit diagram, so all kinds of electrical appliances need various SMT chip processing technology to process. SMT basic process:
Solder paste printing -> parts mounting -> reflow welding ->AOI optical detection -> maintenance -> subboard.
The SMT workshop is mainly equipped with yamaha super high speed SMT SMT machine and general SMT SMT machine, double-track lead-free reflow welding (8-temperature zone), automatic optical detector (AOI), automatic printing machine, etc.The DIP plug-in workshop includes a complete set of production equipment such as plug-in assembly line, AI automatic fitting machine, wave soldering and so on.At the same time, the factory has BGA ball implantation, BGA repair ability, various electronic components QFP, BGA and other special-shaped components (up to 0201) can be SMT processing.
The company has established strict quality control procedures: incoming material inspection (IQC);Printing, gluing, SMT, reflow soldering, IPQC;First piece inspection, complete inspection (QA) as required;Packaging (OQC).At each quality control point, we have determined the personnel and positions, and developed strict inspection procedures and methods.Our quality goal is to have a qualified QA rate of more than 95%, a qualified final inspection rate of more than 99%, and a repair rate of less than 1%.
