What are the Advantages and Disadvantages of the OSP Technology

    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 components together in a very short time, and there will be no organic film remaining on the board.

 

 

Disadvantages:

The protective film formed by the OSP technology is extremely thin and easily scratched, requiring careful operation and operational amplifier. It is also necessary to avoid printing errors as much as possible, because cleaning will damage the OSP protective layer.

 

 

Each surface treatment technology process has advantages and disadvantages, and different technologies are used in different occasions. At present, there is no perfect PCB surface treatment technology that can meet all PCB application scenarios. HOYOGO is an international, professional and reliable PCB manufacturer. Our production strictly follows the high-quality system, all products strictly follow the acceptance standards IPC-A-600-H and IPC-6012, and we can guarantee the quality and reliability of each product delivered to our customers.

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
