The DCDC power module is used for power distribution for its related components. It is just like an adapter. It is the medium between the power supply and the equipment. The quality of the DCDC power module is whether it can be the equipment in a normal environment. Work, so it is very important to choose a high-quality dcdc power module, after all, it can directly affect the operation of the equipment, so how can we choose a high-quality dcdc power module? Here we take a look!


1. Chip components

Chip components are the key to dcdc power modules. The quality of chip components will directly affect the power module.

2. Welding technology

A high-quality dcdc power module has a high-precision welding process. The dcdc power module can be divided into two types: bare board and potting. If the layout of the electronic components is observed in an orderly manner on the bare board, the solder joints The bright, clear and high stiffness indicates that the dcdc power module is durable.


3.Detect aging

Electrolytic capacitors and transformers are temperature-sensitive components and are absolutely related to the quality of power modules. If electronic components and transformers are the most basic test for power modules, then the detection of aging is a more specific test. According to all production batches The power module aging and high temperature sampling inspection can detect whether the quality of this batch of power supplies is reliable and whether the raw materials are safe.
