Here is a tip. Do an evaluation on materials. DO not trust what anyone says about solder paste. There are just too may "experts" out there peddling the brand of the week. You can begin with the brands listed, but do your homework. You know your

Okay, I'm here in Colorado and I used indium 92J and loved it. My test dept. hated it! It leaves a pretty large amount of residue that apparently increased the pin maintenance. The company I worked for actually switched from this paste to another b

Some thoughts of GOLDLAND: We recommend that you choose Vitronics or Heller brands. They are the most popular machines in the world. According to the long-term plan, your equipment needs maintenance and replacement parts in the future, so their parts

Wait a minute I thought I said Celestica and a few others have done the Engineering evaluations on a list of 10 top solder paste's and Indium SMQ92J and Kester's R560&562 came out on top. First you say 'don't trust all of the so called experts on thi

The solder problems that were created caused overcompensation. Plus our PM schedules could be monthly, could be yearly depending on the maintenance crew for a particular line.

Hi Jack, I haven't progressed that much on the reflow project.I'll be working on it in two weeks. Although, I have few vendors that I've been communicating for more info about vapor phase reflow ovens. See the following list: Wenesco Sintronex AICT

How often do you have to replace the blower motors? I will ask the oven manufacturers what the average MTBF is for their blowers. We have numerous BTU's and I don't think any of them have required replacement before 8 years (single shift). Once they

Hi J, Yes, we do too. Funny thing is I was just looking at this last Friday. We call it sharing the bottom of the barrel. Typically it's just Process Engineers stuck down here, but from time to time, Maintenance gets stuck down here too. When in

I have, but not for what you are trying. Different ovens and styles react differently when you try this, so you have to experiment to see how far you can go. Why do you think different temps top and bottom will solve the coplanairty issue? Is this

Hi, The focal point of my research has been to recommend a reflow oven and develop a process for a small to low-medium production SMT soldering with the following considerations. - Lead-Free - Low to low-medium production - Forced Convection reflow
