The assembly time is generally divided into a few minutes of exposure to flux, a few minutes of preheating period, a few seconds of peak period, and a few minutes of cleaning and drying China PCB terminal blocks manufacturers period. They affect all kinds of products, so most purchasing, sales, operators and engineers are quite experienced in this. Keywords: terminal block, use environment, reliability is a very important consideration in business decisions. It will only appear after a period of time, weeks or months of use. During the entire assembly process,
it must withstand the high temperature impact of heat treatment.ca) Translator: Hanjin Xiao, WECO China, Shenzhen Wei Marketing Manager of Kedno Electric Co. In the welding process, infrared preheating and convection preheating are mainly used to conduct heat to the interface of the solder pin and the tin plate to melt the solder paste.
The entire assembly process must be washable with water. Excessive torque or uncontrollable screw tightening will seriously affect the connection performance. If the terminals and packaging materials are to be intact during transportation, they must be resistant to decomposition, deformation, corrosion and extrusion. Its size depends on the following key points. Some professional terms like ‘derating’ and ‘failure rate’ are often used in the field of reliability.
4 exposure to pollutants, dust (conductive or non-conductive), corrosive gas or liquid; 5 exposure to vibration, collision, Penetration, voltage spikes, and current overload environments; 6 principles of derating-when environmental conditions become extremely severe, engineers should reduce the ratings of components; 7 human factors, including regional wiring and torque, installation and maintenance procedures Intensity and misuse in the medium; 8 relevant laws and regulations, some require UL (Underwriters Laboratories),
