How to do quality control for SMT patch processing?

Quality control of electronic processing is an important step to ensure product quality and production efficiency in electronic processing plants. Taking the reflow process as an example, although the temperature in the furnace can be controlled by the fu

SMT patch processing common printing defects and solutions

Right-angle PCB board is easy to produce a card during transmission, so when designing PCB board, it is necessary to do arc Angle processing on the board frame, and determine the radius of arc Angle according to the size of the PCB board.

Eight super details that cannot be ignored during SMT patch processing

Chinese called chip components) installed on the surface of the Printed Circuit Board (PCB) or other substrate surface, by reflow welding or dip welding and other methods to weld the circuit assembly technology.

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

Determine and solve the SMT patch welding method

Control welding temperature: Reasonable control of welding temperature can avoid the formation of bubbles and voids below the solder joint. If the welding temperature is too high, the material below the solder joint will produce gas, resulting in virtual

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
