I had both in time. Both vendors have great machines. Life warranty on blowers, good build quality, good reliability. From this point it will be personal preference on custom details important for you.

Two options: 1 Glue 2 Use a dedicated work holder with 'pockets' milled out to accommodate the components on the first side of the board after reflow. Some prefer a pallet that runs all the way through their process. So, these pallets: * Feature

Something else to keep in mind when you reflow using an IR (non-convection) oven. IR reflow is more susceptible to variations in board mass and coloration than convection ovens. Hi mass areas and dark colored parts will cause more variation in your

What is the most effecient form of heating ,ie calrod, IR, convection , or a mixture ? to produce a good thermal profile on a wavesoldering system on thermally challenging multi-layered boards? Thanks, Adam Adam, I agree with Pete C. Forced co

Look to the no-Pb solderpaste mfr. specs for on-board temps. For example, Indium Corp. has a product that performs at on-board temps of 229C. Now, your BTU oven will handle this no problem, as will most modern ovens. Its all about thermal mass. Look

It seems like the flux is burning-up before the metal begins to flow on this slightly odd component. Alpha talks about alternate reflow recipes for WS609, as follows: * A straight ramp up profile is preferred for reflowing low to medium thermal mass
