SMT patch processing

Factors affecting the pass rate of SMT patch processing

small aperture: most of the metallized holes in SMT are not used to insert component pins, and are no longer welded in the metallized holes

Summarize the packaging of SMT patch processing which is prone to problems

Accumulated service for thousands of electronic enterprises, involving many types of automotive equipment and industrial control motherboard SMT processing services, products are often exported to Europe and the United States, quality can be affirmed by n

What equipment is needed for SMT patch processing?

Welding process parameters: The selection and adjustment of welding process parameters will also affect the quality of welded joints. For example, the adjustment of parameters such as welding temperature, welding speed, crest height and period can achieve

SMT patch processing common professional terms to share

patch inspection: when or after the patch is completed, the quality inspection is carried out for whether there is any missing paste, dislocation, mispaste, component damage, etc.

Adjustment elements of wave soldering process for SMT patch processing

In THT wave soldering, the preheating temperature should not only consider the activation temperature required by the flux, but also consider the preheating temperature required by SMC/SMD itself. Generally, the selection principle of preheating temperatu

The difference between solder paste net and red glue net for SMT patch processing

Solder paste net and red glue net in the material is also very different. Solder paste mesh is usually made of stainless steel. This is because stainless steel has very good strength and corrosion resistance. In addition, the surface of stainless steel is

There are four types of reasons for poor tin penetration in SMT patch processing plants

The selection and control of process parameters is one of the important factors affecting the quality of SMT processing. If the slight difference in temperature or time is not well controlled, it is easy to lead to poor tin penetration and other phenomena

SMT patch processing common short circuit problems and solutions

Patch short circuit refers to the electrical connection between two patches in the process of SMT patch processing. This problem may cause the circuit to work improperly and even cause equipment damage. The main reason for the short circuit of the patch i

Causes of poor welding during SMT patch processing

At present, some manufacturers use non-contact machine vision inspection method for PCB board inspection, this technology because of the high speed and high precision of non-contact measurement and detection, has been trusted by these manufacturers, it ca

What pre-production work should be done for SMT patch processing?

First of all, to perform SMT patch processing, you need to have a dedicated patch machine. Before you start processing, you need to check the state of the mounter and make sure it can operate properly. Checking the condition of the mounter includes cleani

What are the reasons that affect the solder joint glossiness in SMT patch processing

The state of the equipment will also have an impact on the gloss of the solder joint. The cleanliness and maintenance state of the equipment are crucial to the quality of welding. If there is contamination, ash accumulation or damage to the equipment, it

SMT patch processing need to pay attention to several standard issues

SMT patch processing need to pay attention to several standard issuesWith the continuous development of modern science and technology, SMT chip processing technology is also more and more widely used in various fields. However, in the process of SMT patch
