Don't know that oven or if the layout is similar at all to a Heller, but in our 1500s you could lose a blower and not get an alarm until a large board blocked vertical airflow. At that point the thermocouple in the faulty zone would then lose heat

The need to Pre-Bake depends on multiple variables: 1. Packaging from the vendor (dry packs, vacuum sealed, etc...) 2. Storage at your facility (temp, humidity, etc...) 3. Moisture absortion rate of Laminate (FR406BC is one of the highest) Other rea

We ended up switching PCB suppliers and PCB material altogether. We built 400+ units with the new material and got zero delamination. It's still unclear what the real solution is as we introduced two changes at once. This new supplier is going to

Hi Mika, Thanks for your reply. We've managed to narrow down the fault to the control board (long rectangle one in front of the camera). It turned out to be a logic IC that had blown MM74HCT244N (U17 I think). A circuit diagram would be useful beca

Being cynical in a RoHS environment is dangerous; it might lead to "lead" dependency. I know it's not easy to accept the fact that the lead-free alloys and board finishes solder as well as my ceramic bathtub. By the way what do you guys distrust the

Not really. A new Electrovert AquaStorm 100, in-line machine, is under $60K, for straight aqueous applications. The batch type from Aqueous Tech are like $35K I believe. $120K would be for a high performance in-line machine, such as the AquaStorm 200

Well, 60K sounds a little more like it. Yes, it was the 200 I had been sent literature on, but I did kind of figure that the salesman would throw the highest priced equipment at me first, like it was still 1998 and money didn't really mean much. I'll

I am personally in RI, but my HQ is in San Jose, CA. I can get you more information on the machine(s) and configuration you have though, if you are interested. We are also one of the few Used Equipment guys that will sell on terms and stand behind

So, after the repair of a BGA, you notice white reside on a nearby connector. Correct? [Sorry we're so dense. Long day.] Tell us about: * Flux class used in repair * Flux class used in original assembly Why are you baking the assembly after repair

Can someone advise if there is any risk if we use lead-free alloy wire during rework for Leaded Process?The reason for this proposal is to only have one type of solder wire being used in the line.This will eliminate any possibility of leaded wire bei
