Role and selection of air compressor for SMT Placement Machine
SMT pick and place machine also known as “placement machine” and “surface placement system”, is a device for placing surface placement components accurately on THE PCB solder plate by moving the placement head after dispensing machine or stencil printer in the production l...Read more -
SMT AOI machine location on SMT production line
While SMT AOI machine can be used at multiple locations on the SMT production line to detect specific defects, AOI inspection equipment should be placed in a location where the most defects can be identified and corrected as early as possible. There are three main check locations: After the solde...Read more -
17 requirements for component layout design in SMT process（I）
1. The basic requirements of SMT process for component layout design are as follows: The distribution of the components on the printed circuit board should be as uniform as possible. The heat capacity of reflow soldering of large quality components is large, and excessive concentration is easy to...Read more -
How does PCB factory control PCB board quality
Quality is the survival of an enterprise, if the quality control is not in place, the enterprise will not go far, PCB factory if you want to control the quality of PCB board, then how to control? We want to control the quality of PCB board, there must be a quality control system, is often said to...Read more -
Introduction to PCB substrate
Classification of substrates General printed board substrate materials can be divided into two categories: rigid substrate materials and flexible substrate materials.
