High quality control system Advanced SMT technology in Winow pcba China

1.Solder paste printing

 2.apply adhesive

3.using  automated pasting machine to pick up the surface pasting components from the feeder and accurately paste them onto the PCB.

4.Before the component passes the reflow welding, it needs to check whether the component is properly pasted and its position is offset

5. melt the solder on the solder plate with the flow welding process of heat convection technology, and form the mechanical and electrical interconnection between the component lead and the wire pad

6.For through-hole insert components and surface mount elements that cannot be attached by some machines, such as some plug-in electrolytic capacitors, connectors, button switches and metal end electrode elements (MELF), manual insert or component insert with automatic insert equipment.

7.Wave soldering is mainly used to weld through hole inserts.

8.ICT Inspection

9.Defective repair

10.AOI  inspection

11.Cleaning
