There are a lot of benefits of the Inhouse make, such like low production costs, fast work cycles that speed the time to market, safety and environmental protection. But How to assembly an Inhouse PCB board? We are about to take the samples from NexPCB factory to show the whole Inhouse making processes.

1. Prepare tools and materials

1）Printed circuit boards, Stencil, Fixation, Reflower
2）Solder paste, Scraper
3）Tweezers, Solder wire, Electric iron

2. Printing of solder paste

The quality of the PCB is great impacted by the quality of solder paste printing. According to the industry analyst, about 60 percent of the rework board due to the poor printing, this causes our more attention in this process. Three basic steps of printing as following:

1）Fix the stencil in the fixation, place the board under the stencil and align the holes.
2）Scrape the solder paste from the front backwards evenly, the angle of scraper to 45-60 degree is appropriate, then put back the excess paste in the front of stencil.
3）Lift the stencil and remove the board with solder paste carefully, a good print is the final result.
