Hi Scott, My Heller is a bog standard Heller 1500 with an edge guide. There is nothing special about it. I would of course love to have a 7 zone oven, but...I have to use what is here at this time. My only concern with a 5 zone oven is the change i

Hi, It seems weird that an automated pick and place machine at a board shop would not be up to NASA standards, but placing the components by hand would be. However most SMT will self center a bit, so if your close enough, you should be ok. You rea

Key Issue: Will this machine solder your boards? You never know until you solder one. Any other avenues of analysis involve substantial risk. Flux Selection * High or low solids * VOC or VOC-free Solder Alloy * If using lead-free, avoid stainles
