        The PCBA processing process is a very precise process, and it is more complicated and cumbersome, so there will be relatively high defects in the PCBA processing process.  In order to avoid the occurrence of undesirable phenomena and improve the production efficiency of PCBA, various inspections will be carried out in the production process.  first article inspection  and AOI inspection are relatively common. What is the difference between them?   1.  First Article Inspection    The  first article inspection   is done before the mass production of PCBA , and is the   inspection of the   first sample or the first few samples after PCBA processing. Therefore, the so-called "first piece" of the  first article inspection   does not specifically refer to the first product, but usually refers to the first few proofing products after the processing is completed, or it can be the inspection quantity required by the customer.   If the customer does not have a requirement for t

        In the PCBA processing process, welding is a very important process.   If there is a slight negligence in the operation and the relevant process regulations are not implemented, it will cause poor welding. The more common welding defects are: cold joint, false welding, continuous welding, cold welding, less welding, etc. So what is false welding? Why does false welding occur?   False welding means that during the PCBA welding process, although the manual visual inspection has already shown the effect of successful welding, sometimes the leads and solder joints can be separated by  gently poking with your fingers.   That is, it seems that the welding is successful, but in fact the welding fails. Because the false welding phenomenon is difficult to distinguish with the naked eye, it is generally found during AOI inspection.     The main reasons for false welding are welding iron tips, flux, component pins and welding tin quality problems. When the amount of flux is insufficient,

        Looking back on 2023, we have gone through a year of struggle and hard work, a year filled with thorns and bumps. At the end of the year, a year's glory and honor converge here, and a year's bitterness and difficulties say goodbye here. This is a grand gathering of the past and a grand ceremony to look forward to the future.   Firstly, a speech by General Manager Liu: Every annual party is an important day for the company, and we have formed a tradition that the annual  p arty must be held regardless of profit or not. The stage of the annual party gives me a chance to summarize the past and look forward to the future. The past 2023, as I predicted at last year's annual party, was the most difficult year since the pandemic, with all industries facing various difficulties. However, our company was overall stable, with performance and profits basically equal to last year. I am very grateful for the joint efforts of everyone and the trust of each customer over the past

        With the development of science and technology, the volume of PCBA is getting smaller and more precise, and some defects in processing cannot be distinguished with the naked eye, so AOI has appeared.  So what PCBA problems can AOI inspect?   The working principle of AOI is to first collect and input parameters such as images, component positions, solder joints and other parameters of the good-quality board.   During the inspection, the instrument automatically scans the circuit board and automatically captures the image, and then compares the collected data with the pre-entered parameters to determine whether the characteristics of solder joints, components and other aspects are consistent. If the data is inconsistent, the d efect  will be flagged through the display for maintenance personnel to repair.     AOI is mainly used to inspect solder paste printing, component placement and soldering. For example: too much or too little solder paste,   solder paste printing offset;  co

        In the field of electronic manufacturing, with the continuous advancement of technology and growth of market demand, PCB panelization technology has gradually become an important link in the production process .   So do you know what impact does PCB panelization have on SMT assembly?   1.  Why Does PCB Need to be Made by Panel? PCB panelization is to meet production needs. When some PCB boards are too small and do not meet the fixture requirements, they need to be spliced together for production. At the same time, panelization can also improve the welding efficiency of SMT patches, because they only need to go through the SMT process once to complete the welding of multiple PCB. In addition, panelization can also save cost. For example, for some special-shaped PCB board, waste can be reduced through panel production, thereby improving area utilization.     2.  Bad  C ases of  P anel ization   W ithout  S pacing Problem Description: Because the silk screen printing of the compon

       The advancement of science and technology has greatly benefited all walks of life, and the medical industry is no exception.  As medical equipment continues to be miniaturized, its functions are also continuously enhanced to meet the needs of the industry. Ceramic PCB are the core foundation of these devices, do you know why?   1.  Biocompatibility Medical devices often come into contact with human tissue, so the biocompatibility of materials becomes a critical consideration. Ceramic PCB materials not only have stable performance and will not cause allergic reactions, but also do not release harmful substances when in contact with the human body, which provides guarantee for the reliability and safety of medical devices.     2.  High  T emperature  R esistance Ceramic PCB has excellent high temperature resistance. High temperature disinfection or sterilization processes for electronic equipment are very common in medical environments. Ceramic PCB can run stably in higher tempera
