Hi, We tried AIM no clean, and one other paste which I cannot remember the name offhand. We have been using Koki lately, and that's been the best. It seems to leave less residue behind in the stencil. Regards, Grant Petty Blackmagic Design

Hi, Ok, thanks for the info, and I had not considered that factor. Is this an issue related to the reflow temperature change in the oven, or a temperature change in normal product use issue? I will check out the standard, and do you know where it's

Sounds like someone before you was dealing with tombstoning components. We have had greater success with triangular paeratures for 0603 and 0402 footprints. Granted the pad will not be wetted completly but IPC requirements are maintained.

Hi, We had tomb-stoning on a product, and it was quite severe. We eliminated it by reducing the amount of solder paste on the small passible component pads. We used a 5 thou stencil, with 20% reduction, and it eliminated the problem. Regards, Gra

Grant, try TEKA solder-bearing connectors. They have a "brick" of solder that reflows during reflow. They work great! Jason Gregory

Hi, What brand passive components would you recomend for best quality of construction. We are never sure what's good and what's now, and what at some of the better brands. Regards, Grant

Hi Grant, From what I know, it has something to do with the flux...Imagine if the temp difference of the flux is somehow slowed down..it would reduce the tendency of a stronger pull on one side of the pad...

Hi, Thanks and I would be interested to check it out. Can you pass me your email address, as I could not get it. Is there web based info on this? Regards, Grant Petty Blackmagic Design
