Why Does PCBA Need Hand Soldering Processing

      PCBA factory generally use wave soldering for soldering during the DIP soldering technology. This can not only improve the soldering efficiency, but also realize mass production. However, some components that are not resistant to high temperatures cannot be soldered by wave soldering. At this time, hand soldering processing is required - requiring employees to solder with electric soldering irons. Although the speed of hand soldering processing is relatively slow, it is also a very important form of soldering.

 

Five reasons for why PCBA factory use hand soldering processing:

1. Components are not resistant to high temperature

Nowadays, lead-free technology is becoming more and more popular. During wave soldering, the temperature inside the furnace is higher than that of the lead. So, some components that are not resistant to high temperature cannot be soldered by wave soldering.

 

 

2. The components are too high

Wave soldering is also limited to the height of the components. If the components are too high, they will not pass the wave soldering.

 

 

3、There are a small number of plug-in components

In a PCB, there will be some plug-in components on the wave soldered side. If it is a small number of plug-in components, hand soldering processing can be used to improve efficiency.

 

 

4. The component plug-in is close to the process PCB board edge

If the component plug-in position is close to the edge of the PCB board, it will touch the assembly line, which will affect the normal soldering.

 

 

5. Special components

For high-sensitivity components with special requirements from customers, it is also not suitable for wave soldering technology. Hand soldering processing is a very important soldering method in PCBA processing, which can make up for the shortage of wave soldering and improve soldering efficiency.

 

 

In addition, after the hand soldering process is completed, QA personnel are required to conduct a comprehensive inspection to ensure product quality. HoYoGo is an international, professional, reliable, top 15 PCB factory in China, we are committed to providing customers with stable quality, professional PCB manufacturing and PCB assembly services. We have more than 12 years of PCB manufacturing experience. If you have relevant needs, you are welcome to send us an inquiry.

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
