Makerfabs Daily: Solving the Soldering Problem
In the production of Retro, the designer Giles sends us some of the connectors for soldering. 1 year ago, we encountered a problem about the DDR connector soldering problem, that the long connector get bend after soldered.
We solved this problem by designing a special tool to press the connector, to make it not bend in the reflow soldering:
In the recently soldering, we encountered another problem… The HDMI connector also gets bend, as the reflow soldering:
Makerfabs make the following investigations for this:
1) Double checked the soldering temperature, it is right and reasonable:
2) We try to dry this connector in the drying oven, for 2 hours and try again the reflow soldering, but the same thing happens again.
So our conclusion is: this batch connector is a bad quality that can’t bear reflow soldering temperature(245 degrees). As this component is the designer Giles consigned to us via his 3rd party vendor, we report him this problem and our conclusion:
Makerfabs purchased this connector from our vendors, and the final soldering quality much better, and ensures the final production quality.
At Makerfabs, we not only solder the PCBA but also help to check out the mass potential risks for customer design, from components, PCB, to final programming, testing, and assembly.
