Depending on the type of teflon material, thickness, and reflow profile requirements, these will have a direct bearing on your maximum process allowable PCB pallet size. You'll want to be careful on how big the PCB or pallet is. Larger teflon PCBs

JoJo- please keep your "mining" for leads to other forums; you have activated a nearly one year old thread that has no relevance today other than your interest in your making a contact. Try contacting the original poster direct. If you have somethin

Can I use one common cleaning agent to clean the stencils from a lines which are using RMA, No-clean and clean paste ( b'cos we onlyhv one stencil cleaner ). What about those misprinted board ? Can all of them use the same chemical or cleaned in the

Has anyone looked at setup reduction for machine feeders. We have made some gains through changing the flow of work but as lot sizes decrease the number of parts required remains the same. We remove all reels from the feeders after a job is complet

That's what we do with our MSHII's...setup one carriage offline while the other one runs. We also have setup carts to load the feeders ahead of time and haul them out to the lines. Of course, when we exceed the carriage capacity of 75 slots for an

Unfortunately 95% of our runs require both sides of our Universal HSP's. We also have carts that hold one carriage worth of feeders on each side. Parts that carry over from one product to the next are flagged and relocated in the machine per the ne

Great advice!........Single tier feeder set-up carts are also available through Universal instruments directly for this exact purpose. Most people who really care about this changeover time have "pit-crews" that work in the component storage areas, o

I'm trying to design a costing matrix for raw cards so our designers can estimate the costs of their raw card designs, this will hopefully slow down their lust for technology and get them considering project budget costs. Does anyone know of where I

Why not quantify the amount of time spent taping apertures every time you want to use the stencil vs. the cost of a new stencil (about $300, usually)? Look for problems that are created by the blocked aperture method - is there rework down the line t

Boy, does this sound familiar. I agree with Dave, especially his point about board side taping. The kapton tape has a thickness of approximately 2mils. You artificially increase your paste thickness with this method. It also can be a cause for br
