| I was wondering if anybody could give an estimated cost of equipment maintenance per year for a complete SMT line for | a medium volume facility? | Deon Rresponse: Hi John, Your question is very generalized. I think that in order to make a good

| | I am finding that some of our IC's are coming from the supplier with the humidity gauge in the bag reading 10-20%. Has anybody done any tests to determine what humidty level in a package will cause problems during reflow? | | Sound's to me li

| A user of one of our components exceeded the floor life of some plastic BGA components. They did do a pre-bake prior to SMT reflow but only 72 hrs at 40C and not the recommended 12 hours at 125C. I've recommended accoustic microscopy to look for po

| I am starting a new project which involve 3 oz copper layer with 20 mil components on the top of the board and 0.040" thick copper with D2Pak on the bottom of the board. | There is anybody has experience on metal-based PCB reflow process? I guess

| I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a

Thanks a lot,, so assuming we are using standard parts, with nothing out of the ordinary we could safely assume that a machine capable of 20 mil would be more than able to meet our needs down the road. | We are changing from through-hole to SMT, won

| | Has anyone had a problem with the trailer tape length being too short and causing placement machine to stop for parts exhaust (SMT parts)? I realize the EIA spec. is set for this length but would like to know what issues you have had. Thanks |
