As per the title. I'm a manufacturing engineer writing from Italy. We have an old oven ETS/Universal branded that needs to replace a control card. It's an IR lamp oven still utilized to cure glue. Unluckily here there's no more availability of the

Hi there I have a question about reflow oven for Pb-free technology. I've noticed that some of the manufactures offer reflow ovens with short (26-30 lenght in cm) heat zones others offer longer more then 30 cm. So there are ovens with total heat len

Handling a PCB 1. Check your ESD slippers and ESD Strap first before entering the SMT production line 2. A PCB manufactred over 90 days must be stored first on the baking Oven before Production 3. Temperature on the Baking oven must be 125plus and m

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

It looks like the 330 Convection & the GF120 ovens would really stuggle to do lead free, with 3 zones (the 330 has 3 top, 1 bottom). Can't comment on the 545 oven, you'll have to get them to run profiles with a selection of your boards & check on

Try an experiment where you profile the assembly with 3 consecutive boards in the oven spaced just 1" apart versus just 6" apart and then 12" apart. You figure most ovens have about 12 - 16" heating zones, so for your typical 8"x8" PCB, you'd have w

ECD's OvenRIDER is the only instrument I know that can measure thermal transfer efficiency of a an oven. I suppose it would work for environmental chambers too. This instrument has thermocouples to measure ambient temp of oven zones and well as hi-ma

The right way is to know what velocity numbers would net you the required flow for your oven and then measure with a manometer. The required velocity is primarily a function of pipe diameter (and blower rpms) but length and how bendy it is contribute
