For example, welding printed circuit boards for radios and televisions and their maintenance. Operation of printed circuit board assembly products.
Xinchang Electronic Technology mainly engages in SMT mounting, PCB circuit board welding, PCB circuit board mounting, etc. in Wuhan, with 20 years of research and development and production experience.
If there is a temperature controller, it will reduce the temperature to a very low temperature within 30 minutes of ambient temperature, let it cool down, and then return to normal.

Low dielectric loss, waterproof, oil proof, radiation proof, condensation proof, salt spray proof, conduction proof, insulation resistance of 70 ° C, and voltage resistance of 1500V.
Connect correctly. After connection, discharge 3-5 times according to the specified time and environment. To facilitate personnel protection. After discharge, it should be cooled immediately.
Grounding protection should be provided for equipment with enclosures. When the AC power transformer is connected to the ground, due to its fine wire diameter, the bus voltage should not exceed the insulation strength limit value and must be well grounded. If the grounding of the casing does not meet the specified requirements, testing must be conducted before proceeding.
The size of the power supply is influenced by the size of the AC power transformer. When using a low-voltage AC power supply, its voltage to ground is relatively small, generally not exceeding 12V. In order to meet the conventional low-voltage power supply system requirements in the local area, people usually use positive grounding and quad wiring methods.
When considering factors such as job technical performance and design, the most important factor that design engineers need to consider is the minimization of the system and the susceptibility to technological influences.
