For the majority of small and medium-sized contract manufacturers or production plants, cost considerations often lead them to use traditional manual brushing cleaning methods. This involves using an antistatic brush dipped in cleaning agent to brush the PCB. The PCB is tilted at a 45° angle, and the brush is moved from top to bottom,…
With the increasing use of chips, many EMS factories have large quantities of damaged BGA chips waiting for repair. If manual BGA soldering is used in such cases, the labor cost will be very high. In such situations, it is necessary to use fully automatic BGA rework stations for repair. Does this mean that manual…
With the rapid development of the BGA rework industry in recent years, the use of BGA rework stations has become increasingly widespread. For those within the BGA rework industry, I believe everyone knows what a BGA rework station is because some people deal with it every day. However, for those outside the BGA rework industry,…
As a manufacturer of selective wave soldering equipment, it is essential to provide an explanation of the selective soldering process. This will facilitate the understanding of the working principle, advantages, and market prospects of selective wave soldering for the departments considering its use. The increasingly fierce competition in the electronics market has brought significant quality…
Selective wave soldering is a process used for soldering electronic components. It is suitable for circuit boards that are not suitable for traditional wave soldering, such as complex circuit boards with a large number of surface mount devices (SMDs). Here are the steps of the selective wave soldering process: Selective wave soldering process offers advantages…
The increasingly competitive market for electronic products has put significant pressure on electronic manufacturing companies in terms of quality and cost. The trend towards high density and miniaturization in electronic device production processes has propelled the rapid development of SMT (Surface Mount Technology) processes, with selective soldering experiencing a period of high-speed development. Below is…
Cleaning steel mesh typically involves manual cleaning or using specialized steel mesh cleaning machines. Nowadays, factories primarily use steel mesh cleaning machines, such as the Silman Tech Steel Mesh Cleaning Machine C730, which can clean various types of mesh boards. During the steel mesh cleaning process, it is important to ensure that the air pressure…
Setting appropriate temperature profiles is crucial for successful BGA chip soldering using a BGA rework station. The temperature profile for BGA rework stations generally consists of five stages: preheating, ramp-up, soak, reflow, and cooling. Let’s delve into each stage in detail. By adjusting the temperatures in each stage based on the PCB characteristics, the optimal…
Regarding laptop repairs, due to the high integration of laptop motherboards, the difficulty level of repairs is higher. Especially when it comes to IC chips with “BGA” packaging, it can be quite challenging for many repair technicians. Below is a brief introduction to the specialized equipment for repairing graphics card BGAs and the cost of…
There are generally two types of BGA soldering equipment: BGA rework stations and manual hot air rework stations. The choice depends on the user’s specific requirements. Manual Hot Air Rework: BGA Rework Station: These are the two most common types of BGA soldering equipment. Users can choose the one that best suits their needs.
