Why would you have troubles if and when you switch? Isn't that the point of materials evaluation? Understanding the impact and material capability BEFORE "betting the farm on it". I would never stake my career on a solder paste without an Engineer

What is the year, make and model of your oven? Are you running it with Upstream and Downstream (pre-reflow, post-reflow) conveyors? Is the qty of the product low, medium or high? What is the max process width of the oven? what is the max board with o

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

Who said there was NO evaluation? The paste we chose was evaluated based on a 20 point test score as well as material compatibility. Once we introduced it to manufacturing each line had problems. For one manufacturing treated it as a drop in repla

As far as solder paste goes search no further! I have worked for some huge CM's as a Process Engineer and a lot of them have put thousands of hours of Engineering time and evaluation just to come up with the same answer every time. For no-clean it is

Kelly, it's been a long while since I repaired a BRAVO. The machine was a little unique as far as Electrovert ovens go. I am pretty sure that it is the only Speedline model that integrated a PLC. Loved the OMNI's, not so much with the Bravos. I a

Hi Danny Just let me know if you get some Vapour Machine Vendors bcoz we plan to change from our reflow process to vapour process. Appreciated in advance. Jack

Absolutely ok!! We already co-use the same profile setting for top and bottom side to avoid line efficiency loss for more than 10 years. But only one thing you should careful is the heavy mechanical parts on bottom side may drop during reflow proces

That is why we don't care if it is Top or Bottom. We call them first (process) side and second (process) side. Often you will have tall and heavy parts on both sides, so you will have to glue them.
