SMT patch processing includes equipment and manufacturing processes
SMT SMT processing includes the following equipment: 1, board machine: 2, solder paste printing machine, 3, SPI(3D solder paste detector) : 4, SMT machine, 5, the first piece of detector: 6, reflow welding, 7, plate machine: 8, AOI detection, 9, X-Ray
How to deal with SMT patch bulk material?
The advantages of PCBA processing clean free technology: 1, a large amount of saving cleaning labor, equipment, site, material (water, solvent) and energy consumption; 2. Save working hours and improve production efficiency; 3, advanced production technol
Specification for PCB storage and inspection in SMT factory
PCB inspection contents: ① appearance inspection: ② size measurement: ③ furnace temperature test: ④ pad welding force test: ⑤ Check the PCB board factory report
Influence of SMT material on welding quality of PCBA
When the welding ends or pins of components are oxidized or contaminated, welding defects such as poor wetting, virtual welding and voids will occur in reflow welding. Poor coplanar properties of components will also lead to welding defects such as virtua
PCBA processing and SMT processing difference
PCBA processing and SMT processing differenceThe whole process of PCBA processing actually includes SMT patch processing. SMT patch processing is only part of the PCBA process, which literally means a wider range of processes
SMT SMT machine core technology explanation
The requirements of the mechanical motion part of the SMT machine are as follows: 1. Design, manufacture and assembly technology of micro, precision and high precision mechanical parts; 2, sports machinery express response, low loss, high efficiency, prec
SMT patch processing technology points
Key points of solder paste printing technology: 1, the Angle of the printing press scraper and steel mesh, 2, scraper pressure, 3, scraper speed, 4, printing gap, 5, release speed
What are the SMT patch production line equipment
SMT production line has a lot of equipment, and different production lines need to place different equipment, mainly divided into semi-automatic SMT line and automatic SMT line.
Fully automatic SMT manufacturing
PCB design must meet the requirements of SMT equipment, otherwise it will affect the production efficiency and quality, and may even be unable to complete automatic SMT by computer.
How does SMT affect PCB production time and speed it up?
By using SMT, the PCB does not need to be drilled into it. Instead, what they do is they use solder paste. In addition to adding a lot of speed, this simplifies the process significantly.
What inspection should be done before SMT patch processing?
What inspection should be done before SMT patch processing: first, SMT patch components inspection, second, printed circuit board (PCB) inspection, third, SMT patch processing precautions
