Most mass-produced electronic hardware today is manufactured using surface mount technology or SMT. The Surface Mount Technology: The concept of basic surface mount technology (SMT) basic through-hole fabrication continues to provide significant improvements. By using SMT, the bare board pcb does not need to be drilled on it. Instead, all they do is use solder…
Many engineers do not want to see a short circuit in the PCBA. What should I do if the immersion gold fr-4 pcb is short circuited? Why is there a short circuit on the circuit board, and if there is a short circuit, how can we troubleshoot it? There are usually two short-circuit situations. First,…
The development path of SMT proofing and small batch processing has developed rapidly towards the direction of high density. With the development of electronic technology, the market also requires more miniaturization and precision of electronic products. Nowadays, the technology of SMT chip processing is more and more widely used in the electronic industry. In order…
PCB product testing is a critical step in ensuring surface mount reliability. With the continuous development of PCBA manufacturing industry and the increasing improvement of core technologies, the assembly density of shape memory alloys is also increasing, which not only brings about fine lines of circuit patterns, fine pitch of patches and non-visual characteristics of…
The common detection methods of PCB Circuit boards in the production process are as follows: 1. Manual visual inspection of 94v0 PCB board Using a magnifying glass or calibrated microscope, operator visual inspection to determine if a circuit board is out of order and to determine when corrective action is required is the most traditional…
How to Avoid PCB Soldering Defects? 1. The solderability of the pcb circuit board holes affects the soldering quality The poor solderability of the circuit board holes will cause virtual welding defects, affecting the parameters of the components in the circuit, resulting in unstable conduction of the components and inner layers of the multi-layer board,…
Surface wetting of SMT chip proofing refers to a phenomenon when the solder spreads and covers the surface of the metal to be soldered during soldering. The surface wetting of SMT chip processing generally occurs in the case of close contact between the liquid solder and the surface of the metal to be soldered, and…
The solder paste printing machine is an indispensable processing equipment in the SMT small batch chip processing factory. The quality of the solder paste printing can directly affect the quality of our SMT chip processing. Now in many processing plants, automatic solder paste printing machines are more and more used in industrial production. When the…
With the development of electronic technology, many electronic products are developing in the direction of miniaturization and precision, and the requirements for SMT chip processing will become higher and higher. Welding requirements and conventional welding process, the welding of components, the main attention is: master the heating time, use the appropriate temperature and good operation….
The reflow soldering process is a very important process in the welding stage in the small batch processing of SMT proofing. The quality of the small batch processing of SMT proofing depends largely on the welding quality, and the reflow soldering process will directly affect the quality of the patch welding. Electronic processing plants must…
