The principle of the chip processing factory’s quotation for SMT chip processing With the prevalence of the Internet era, the division of labor for enterprise specialization has become more and more important. PCBA electronic product processing manufacturers will get more customer inquiry opportunities. At this time, how to make PCBA quotations in a targeted manner […]

The sequence of COB bonding processing and SMT processing in PCBA processing In general PCBA processing, before COB processing, SMT patch processing must be completed. This is because SMT processing needs to use steel plate (stencil) to print solder paste, and the steel plate must be laid flat on the empty circuit board (bare PCB). […]

Introduction of the three anti-paints used in PCBA processing Friends who have been in the PCBA processing industry know that according to the environment in which the terminal product is used, there will be different requirements for PCBA processing (commonly known as circuit board processing). For example, the circuit board needs to be painted with […]

Humidity sensitivity in the SMT patch processing process harms product reliability When the MSD is exposed to the atmosphere, the moisture in the atmosphere will penetrate into the packaging material of the humidity sensitive device through diffusion. After the device is mounted on the PCB through the patch, it must flow into the reflow oven […]

AOI optical inspection equipment is an important equipment to ensure the quality of SMT patch processing Today, the editor and you are introducing the most important equipment for quality assurance in SMT patch processing-automatic optical inspection equipment (AOI). Automatic optical inspection (AOI) has become an indispensable process monitoring method in the SMT industry. In most […]

Before cob binding processing, you can first understand the process of cob binding processing The first step, first understand the technical parameters of keyboard COB binding processing and detailed introduction of COB binding processing in detail; The second step is to look at the comments and online messages of netizens who have purchased COB binding […]

How to deal with defective SMT patch processing The main maintenance methods of SMT patch processing include: soldering iron, focused IR and warm air. Warm air and focused IR are generally composed of a bottom plate and a furnace. The function of the bottom plate is to radiate heat to the printed circuit board, and […]

SMT processing factory’s operating rules for PCBA patch processing 1. There should not be any food or drink in the PCBA work area, smoking is prohibited, no sundries that are not related to work should be placed, and the workbench should be kept clean and tidy. 2. During PCBA patch processing, the surface to be […]

Several methods to prevent PCB printed board from warping 1. Why the circuit board is required to be very flat 　　 On the automatic insertion line, if the printed board is not flat, it will cause inaccurate positioning, components cannot be inserted into the holes and surface mount pads of the board, and even the […]

SMT patch workshop PCBA board inspection project standard 01, SMT parts welding spot welding 02. Cold welding of the solder joints of SMT parts: use a toothpick to gently touch the pins of the parts, if you can pull it, it is cold welding 03, SMT parts (solder point) short circuit (tin bridge) 04, SMT […]
