The importance of DFM in the production process of SMT patch assembly According to many years of electronic production experience in Dongguan SMT processing plant, the design cost of the product accounts for more than 70% of the total production cost. The costs incurred during the specific production process, such as operating expenses, materials and […]

SMT chip processing reflow welding welding defect inspection checklist 1. Pickaxe bead checklist (1) Is the temperature rise rate in the initial stage of preheating too large? (2) Is the temperature rise rate during the reflow phase too large? (3) In order to avoid tin bead, has the template opening size been reduced or the […]

How to solder SMT chip processing components and lead components SMT chip components are particularly small in size and light in weight, and chip components are easier to solder than lead components. SMD components also have a very important advantage, that is, it improves the stability and reliability of the circuit, and for production, it […]

In SMT chip processing, chip inductors mainly play the role of choking, decoupling, filtering and tuning. There are two types of chip inductors, winding type and laminated type. How to choose suitable chip inductors? How should the performance and appearance quality of SMT components be tested? SMD inductor selection: 1. The net width of the […]

Analysis of the causes of component displacement in SMT chip processing The main purpose of SMT chip processing is to accurately install surface mount components on a fixed position on the PCB, and some process problems sometimes occur during the chip processing process, which affect the quality of the chip, such as the displacement of […]

Control the quality of SMT patch processing from production management It is undeniable that quality has always been the fundamental development of an enterprise. Whether it is the entity Wanda or Alibaba’s e-commerce empire, quality has always been the focus of the public. As a leading company in the field of SMT patch processing, Yitai […]

The flux that is rather short-lived in smt patch processing Flux is indispensable in smt patch processing. A suitable flux can not only remove oxides and prevent re-oxidation of the metal surface, but also improve solderability and promote energy transfer to the soldering area. Choosing high-quality flux is the secret of Jingbang Technology’s brand building. […]

Analysis of the causes of printing defects in SMT patch assembly 1. Solder paste collapse and blur in SMT chip processing 1. The hardness of the scraper is too small, and the backside support is insufficient. The low hardness of the squeegee will cause the solder paste to be difficult to form, and the printed […]

The requirements of SMT processing technology for component layout design The layout of components should be designed according to the production equipment and process characteristics of smt patch processing. Different processes, such as smt patch reflow soldering and wave soldering, have different component layouts: when double-sided reflow soldering, there are also different requirements for the […]

What are the common problems in SMT patch processing Common problems in MT patch processing: 1. There are no mark points and process edges on the PCB. It will cause PCB components on the track side of the SMT placement machine to fail to paste. The lack of mark points leads to low correction accuracy […]
