Jim, We have an SRT Summit 1000. It's a nice machine, but may be overkill if you're only looking to place and remove small quantities of BGA's. In 4+ months of use, we've had good success placing and reflowing a variety of BGA's including UBGA. Suppo

| HASL: (hot air solder leveling) is a process used to cover the Cu. Either Sn/Pb is used or Ni/Au or some other combo. In one case you create a land pad and in the other (with resin)you cover the Cu so that you only have a "trace." Is that correct s

| I wonder if the attitude of some manufacturers gets acceptance from their customers. Some say, if they did not earn selling a machine then they also don't want to service it. | Does this affect users? Do you rather choose other manufacturers if you

Why do you think that assembling the BGA, QFP, and fine pitch parts will solve your bridging problem? I would think doing this may cause you more grief by having these more massive components being reflowed upside down fall off during the second pas

Hi, thanks for your input. Yes, we do have a rework station - specifically a SRT Summitt 1000 station, but it causes us many problems and is down more than it's up...I do not think that using it would speed up the process at all. As far as accuracy

Consider: * Quitting the coating business all together and using a coating service supplier, like: Thermospray Co 800-952-5838 Mike Moninger; Advanced Coating 800-722-1444; Epsco 108 W. 37th St Boise Idaho 83714 (208)389-2000 * Buying a programmable

Check : 1) design aspect ratio / are ratio required to fabricate the stencil you r using. 2) check if the stencil maker is using your checked aspect ratio / area ratio? if not the same, what are they using? any QA report confirming actual dimension

My two Process Engineers are at odds with each other. One says that the Tact Time is only the actual Pick-n-Place time to build a board, and the other says it needs to include the load/unload time as well as the Fiducial reading time. Example: So
