I am using the smallest sized readily available lead paste I could find (15-25 micron size) and printing using a metal stencil with the smallest pitch being .5mm pitch qfns. Reflow is with a SMTmax ...
A standard reflow method for low-volume assembly is: Method A Apply solder paste (using stencil or syringe) Hand-place parts (using vacuum pickup pen or tweezers) Oven reflow - But what happens ...
Basic question here, but it's driving me insane! The solder does not seem to stick to the tip of my soldering iron. After the iron heats up, the tip appears black (sometimes on all sides and ...
I'm new to SMD soldering, and tried to assemble a couple of boards, using a reflow oven. I 'm using a stencil (Kapton - mylar) and so far it worked fine except for the LQFP48 devices (pitch 0.5mm). In ...
Wave soldering I am trying to understand how wave soldering works. Unfortunately the Wikipedia article has has left me unsure about the process: Is the entire board with its components ...
Got inrested in DIY fluxes by reply here. Can you substitute rosin-core wire with DIY flux and non-rosin-core-wire? How and where to actually use DIY fluxes if you have rosin-core wire? Which % of ...
I'm soldering up some boards with smd parts, using a hot plate to reflow, and I'm (inevitably) realizing that I got some of the wrong parts. Now, is it better to leave the boards with smd components ...
