What is the Role of the PCB Break Away Tab?

     The PCB break away tab is not part of the PCB, and its existence will consume more boards, thereby increasing the cost of the board, so we need to remove it after the PCBA processing is completed. But even so, the PCB still needs to retain the existence of the break away tab during production, which shows its importance. So what is the role of the PCB break away tab?

 

 

 

During the SMT placement process, the PCB board is conveyed through the guide rails of the machine. If the break away tab is not reserved, there will be a phenomenon that the component is too close to the edge of the PCB board when mounting, and when the component is beyond the scope of the PCB board, it will not be possible to mount and solder normally. Therefore, the function of the break away tab is to expand the distance between the components and the equipment to assist the board routing and ensure the normal operation of the SMT placement process.

 

 

The flatness of the PCB break away tab is also a part that needs to be controlled in PCB production. When removing the PCB production break away tab, it is necessary to ensure the smoothness of the break away tab, especially for PCB boards that require high assembly accuracy. Any uneven burrs will cause the mounting holes to be offset, which will bring inconvenience to the subsequent PCBA assembly and processing, and the method of removing the break away tab is the same as that of the PCB splitting.

What are the Advantages and Disadvantages of the OSP Technology

图片
     With the continuous development of the electronics industry, there are more and more PCB surface treatment technologies, and each technology has its own merits. OSP is a commonly used surface treatment technology process, what are its advantages and disadvantages?       Compared with other surface treatment technologies, OSP is somewhat different.  It uses a chemical method to produce an organic film on the clean bare copper surface, which acts as a barrier between the copper and the air.   OSP is organic, not  metallic,   and its cost is lower than most surface treatment technologies.     Advantages: With this organic film, it can resist the attack of moisture in the air without being oxidized before welding,  can withstand the test of high temperature, maintain good activity, and has a good tinning ability.  This layer of organic film will not cause damage to the sheet material. It can be easily removed by the solder resist during soldering. It can solder the copper wire and the

What PCBA Problems Can AOI Inspect

图片
        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

The Role of Shield Cover in PCB Design

图片
  SHENZHEN HOYOGO ELECTRONIC TECHNOLOGY CO., LTD. specializes in providing overall PCBA electronics manufacturing services, and can also provide customers with a full range of value-added services: including SMT assembly, PCB program development, schematic design, PCB layout and routing, Bom list matching, component procurement and other services. Do you know the role of shield cover in PCB design? What is a Shield Cover? The shield cover is an alloy metal cover, which is a vital component to reduce the radiation of the display. It is used in MID or VR products, which can effectively reduce the mutual interference between modules. It is common in the isolation between the main control function module and the power module and the Wifi module. The  P urpose of  S hield  Cover   C lip Generally, there are products that use wireless communication, and shield frames are usually designed on the circuit board to isolate electromagnetic interference (EMI). However, to make the shield frame fun
