Hi, Can anyone help me on how to choose profile points in wave soldering...e.g. smallest like R, C, to biggest like transformer heatsink etc.... Are the thermo-couples supposed to be on top of the pcb or at the bottom touching the solder bath when fl

NJEV- You can contact me off line for my opinion on the Easi line :caldon@smtnet.com. Compared to past products this one was weak. Missing parts, Screws sticking out, the thermo-sensor was right next to the button so the longer you held the button th

Hi Wow, Quite elaborate. My Mechancial Engineering, Thermo friends would be proud of you. I am not kidding. The only problem I have with your technique is that quite often internal lands and structures steal the heat during soldering. By your techn

Thanks for the response Dave. FYI: In my experience using the light cure adhesive, I have found that the newer the adhesive is the less prone it is to popping off during a reflow cycle. Also I have found that it only takes a very small amount to sec

Hi there all, we are having problems with 2 qfp devices. grainy poorly reflowed solder joints. One 100 pin .5mm pitch, and one 64 pin .5 mm pitch . Both of these devices have a thermo pad on the back of them (pad area soldered to back of device)which

Hi SMT Engr With a double-header connector do you mean Double Level Right Angled Header Connector. If so there is a big difference in heat sinking capacity between the two rows, as where the pins of the top connector absorbes twice as much heat as t

You might consider installing a noise kit as it sounds like you've tried almost everything else. Electrical interference on these machines causes erratic problems, especially as they get older. I would call Speedline tech. and see if they think the
