Automatic dip tin machine common problem one: poor contact
The metal conductor inside the terminal is the core part of the terminal, which transmits the voltage, current or signal from the external wire or cable to the corresponding contact of the matching connector. Therefore, the contacts must have excellent structure, stable and reliable contact retention and good electrical conductivity. Due to the unreasonable structural design of the contact parts, the wrong selection of materials, the unstable mold, the excessive processing size, the rough surface, the unreasonable surface treatment process such as heat treatment and electroplating, improper assembly, poor storage and use environment and improper operation and use, the contact parts will be damaged. Contact parts and mating parts cause poor contact.
Automatic dip tin machine common problem 2: poor insulation
The function of the insulator is to keep the contacts in the correct position, and to insulate and protect the conveyor from each other between the contacts and between the contacts and the housing. Therefore, the insulating parts must have excellent electrical properties, conveyor protection mechanical properties and process forming properties. Especially with the widespread use of high-density, miniaturized terminals, the effective wall thickness of the insulator is getting thinner and thinner. This puts forward more stringent requirements for insulation materials, injection mold precision and molding process. Due to the presence of metal excess on the surface or inside of the insulator, surface dust, flux and other contamination and moisture, organic material precipitates and harmful gas adsorption film and surface water film fusion to form ionic conductive channels, moisture absorption, mold growth, insulation material aging and other reasons, Will cause short circuit, leakage, breakdown, low insulation resistance and other poor insulation phenomena.
Common problem of automatic tin dip machine three: poor fixation
The insulator not only acts as insulation, but also usually provides accurate alignment and protection for the protruding contacts, and also has the functions of installation and positioning, locking and fixing on the equipment. Poorly fixed, the light one affects the reliability of the contact and causes an instant power failure, and the serious one is the disintegration of the product. Disintegration refers to the abnormal separation between the plug and the socket, between the pin and the jack caused by the unreliable structure of the terminal due to material, design, process and other reasons when the terminal is in the inserted state, which will cause the control system computer to peel off. Serious consequences of interruptions in electrical power transmission and signal control. Due to unreliable design, wrong material selection, improper selection of molding process, poor quality of heat treatment, mold, assembly, welding and other processes, and improper assembly will cause poor fixation.
