The driving part of the wear mechanical drive to drive the feeding mechanism by the CAM spindle, quickly knock to find SMT feeder strike arm, through the connecting rod so that the ratchet connected with the components to drive the braid forward a distance, while driving the plastic coil to br...Read more -
What is the Replacement Process of SMT Feeder?
1. Take out SMT Feeder and take out the used paper plate. 2. SMT operator can take material from the material rack according to their own station. 3. The operator checks the removed material with the work position chart to confirm the same size and model number. 4. The operator checks the new pal...Read more -
Six Methods of SMT Patch Component Disassembly(II)
IV. Lead pull method This method is suitable for disassembly of chip – mounted integrated circuits. Use an enameled wire of appropriate thickness, with certain strength, through the inner gap of the integrated circuit pin. One end of the enameled wire is fixed in place and the other end is ...Read more -
Six Methods of SMT Patch Component Disassembly(I)
Chip components are small and micro components without leads or short leads, which are directly installed on PCB and are special devices for surface assembly technology. Chip components have the advantages of small size, light weight, high installation density, high reliability, strong seismic re...Read more -
How to Reduce Material throwing Rate in SMT Production Line?
I. In order to eliminate SMT machine production process of high material throwing rate, it can not ignore the human factors, such as the common cause of high material throwing rate of the operation is the operator when the installation of material tearing belt is too long and too much pressure, t...Read more -
