Does anyone know of a splicing machine? We have the hand held tools but are looking to do much higher volume now. We are soon going to take full reels (5000 pc) and split them into 1000pc reels (mainly because they are needed on more than 1 job) so w

Were looking for the Hollis GBS Mark III ladder code for the GE Series One PLC or a CPU module from a GBS system we can download from or buy outright. We have lost the application code from RAM and need to restore or recreate it. Bob

You may want to clarify how much $$$ you have. If you look at a quad 4C call PPM, I believe they have a windows based operating system now. I think a 4C with some feeders would cost you $5K to $20K depending on condition and feeders. I believe you wa

I was asking about delta t in profiling, because I have just started to learn how to do it and wanted to know about it. So how can you reduce delta t, so you dont go from cold to hot too fats. Is it enough to slow donw conveyor speed??? Thanks M

Good points on both subjects. Not all who talk engineer speak are engineers. It depends on how shiny their shoes are. Delta T across any medium can mean a myriad of different set values. From Polynomial Expressions to the names of any organization

Rather than go into detail here, try googling "classic reflow profiling". One of the guys at ECD (a thermal profiler manufacturer) wrote a pretty decent article that covers most if not all of it. You DO have a profiler, don't you, or an oven with

It's an Horizon (01) with large board (24" x 30")capability. Some software issues, as the OEM stopped progressing software on this machine (an offshoot of Horizon 7SP02) and never made final release Typhoon software compatible with this (Same with Vi

I think the not fully melted BGA ball is the main problem. The middle of the BGA IC...the ball not fully melted....when it subjected to heat and cause PCB warpage....the partial melted joint in the middle part of the BGA started to crack...bcos of we

Is your data scewed in any fashion? If not the board is fine. If the cosmetics are an issue, write a procedure to have them changed out based on the criteria you choose (testing results, cosmetics etc.). This will be essential if your company is ISO

With a 7 thou stencil, we'd go 1 to 1. So for a more typical 6 thou stencil, we'd bump the aperture area by 1.15, maybe 1.2. We make no distinctions between 'innies' and 'outies'. Are you talking about castellations on land grid devices [ie, BCC�, L
