We are in the process of qualifying our SMT lines for the High Melting Point Solder with alloy composition of 93.5 Pb 5 Sn 1.5 Ag.If any one has already an experience with this alloy,kindly do give ur inputs on the process of profiling . The reflow d

I'm having a fun time between BGA rework/repair using an SRT 1000 and SPC efforts (much easier) using DEK stencil printing processes and BTU reflow with 6 Fuji lines in between. Concerning the BGA stuff, I'm getting about 60% success using this rewo

My company is looking to perform "real time" statistical process control on our current SMT operations. I have identified the critical processes for SPC but have not had much luck in finding a system(s) that can monitor the required processes for my

Tony--Good morning. We deal in used and refurbed equipment and have a nice Panasonic line available now w/ DEK 265 printer, Pana PFA MV2CXL chip shooter w/ +(130) feeders, Pana MPA3F w/ +(60) feeders, BTU VIP 70 Reflow, several pieces of input and bu

Ive a 5 zone vip 90, running at temperatures up to 280 degrees, biggest problem we have is with the fan moters siezing up. think we must have changed 8 out of 10 of them ok there 10 years old but it can be a lot of hastle. they sieze absolutly solid.

If it's really low volume I would only invest in a stencil printer and convection reflow oven to start with. If you want to go really low budget get a manual unit such at one from Transition Automation. Make up some really good shop aids and have s

Hi Mark, Check out Heller's white paper link for a study done with a PCB in line with thick and thin aluminum plates to measure repeatability and delta T with loads of large mass materials. The result was less than 1 degree with their oven due to i

I just ran into a reflow profiling problem with a new assembly that we are processing in SMT. There is a cluster of six or so electrolytic caps that measure approx. .710" wide by .660" tall. They are spaced .100" or so apart. When I run a profile, t

It depends on a number of factors - including as Russ pointed out, complexity (sometimes you need to create very complex profiles if you have large BGAs and other such components, which require at least 7 heated zones), then you have size, required l
