Qinsi-QS5100 Sn63Pb37 solder profile

Qinsi-QS5100 Sn63Pb37 solder profile

Alan Hawse from IOT Expert writes, “About 2 years ago, I bought a Qinsi QS5100 reflow oven from China via Amazon.com.  My decision was based almost completely on the nice youtube video that Ian Lesnet from Dangerous Prototypes posted about his results.  After I got the oven, I successfully built a series of Physics Lab boards with it.  Then one day about a year ago, I got two boards in a row with horrible results which I attributed to the temperature profile.  A few weeks later, I dug around on the internet and decided to change to the Lesnet profile and things seemed to be working again.”
