We have these thin and flexible sheets of fiberglass that we sometimes use to send boards through reflow that can't ride the edge hold fingers. We've had these sheets for a decade at least and have no idea what they are or where they were purchased

Rob, We are also using intrusive reflow to simultaneously process SMT and Thru-hole components. Our arrangement goes as follows: - Screen print solder paste to the single sided PCB using 0.008" laser cut stencil. - Apply adhesive dots to selected

| Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | 1. Cpk's

What kind of problems/defects/process indicators are you having? It is likely that you will have to bite the bullet and get a thermal profiling mole to prove that your selected profiles are subjecting parts to the correct tempertures per part specs.

Another critical part of a process with a large board is support. Most commonly this is a bed of pins e.g something like red-e-set but there are other solutions. Support with a large panel will be critical for printing to get a good gasket between PC

Hi Marc I too have been using a fully synthetic Motor oil on Heller reflow ovens for a number of years. In our case Mobil 1 5W-50. We have a field failure problem with some 1% resistors under conformal coating where sulphates are dissolving the si

Our company doesn't need a huge 10 foot reflow oven blocking up space on our shop floor. We have been looking for 1 backup tabletop unit and 1 compact conveyor unit made by a reputable manufacturer. For tabletop units the only non chinese I keep

Hi davef, couple of questions: clarifying costing of direct labor against overhead cost: an operator loading PCB onto the reflow oven is a direct cost, how about the reflow process time of the PCB while travelling inside the reflow, is that an ove
