Regardless of what people tell you, there is only one way, I will repeat it ...."ONE WAY" to have void free solder if using flux. You must have capitol equipment capable of pulling a vacuum as soon as the solder reaches liquidus state. (Pink oven or

Normally,titration kit is used for low solid flux,provides a more accurate method to determine the flux concentration so as to assure consistent soldering results.There are three chmicals in the process.test kit solution,indicator and your flux.add d

Experts, Today I received PCB in a punctured vacuum seal bag. the Humidity indicator change the colour to pink at 60%RH mark. The brd finish is Entek. Earlier our intention to get the board vacuum seal is because we want to ensure that the is no fr
