| | 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

I spent 25 years operating my own hybrid shop working with surface mount components, soldering materials and procedures. Dealing all the while with it's associated surprises and problems such as yours. Now-a-days I get paid to investigate and attemp

Hi Sal I've used the Stevens product for about 5 years and have nothing but good to say about them. pallets? can't say. The gloves simply extent the finger length by about 0.04" They come in 15" sticks so the length is up to you. Print/reflow contam

I admit, 16 mil QFP printing is very challenging but if all your control factors (print speed, etc...) are setup correctly (through DOE) extremely high yields can be achieved and more importantly a repeatable and robust product will be manufactured.

Dave, I think we are heading toward the same objective, but from different directions. You are asking what's the cost of ownership? However, I think a question that is just as important and one that is pertinent to your current economic picture is,

My first comment is "Buyer beware". I think that there is enough skepticism already from potential end-users that we are all maybe too wary. I endorse the concept, it has tremendous potential for process improvements, and making life easier. I have b

Steve What do you mean by better? More/less activity? fewer retouches? longer shelf life at ambient temperature? less hygroscopicity? longer open time on the stencil? easier to wash? easier to treat waste water? easier for washing machine maintenanc
