| Anyone have an idea how small a via must be to inhibit significant solder volume escaping into the via? Typically, micro vias are drilled and plated to about .003" diameter. To avoid significant solder "drain off," they should be drilled as shallow

| Maybe I'm doing something wrong, but it seems to me that The Forum takes a lot longer to open up now. It also takes a lot longer to get back to the main Forum page, after reading an individual message, and hitting the "BACK" button. What's up? Is

Hello, I know nobody asked, but here are my 2cents on the newer, more comercialized layout of the forum. I frequent many of the SMT/Assembly forums and the ones I prefer to stay with are the ones that are NOT comercially oriented. Not having comercia

Just a comment to clarify this discussion. Typically chip caps and other passive components that use palladium plated to the end of the component are very different from the TI nickel/palladium plated IC components (leaded devices). The main di

Adam- Mikie here. I too am placing 2 PBGA sockets on an assembly but they aren't mirror imaged. Thanks to the SMT Gods for that one. You say you added more paste to solve for open solder. Do you have x-ray? Were the alignments perfect? Also the part

IPC-D-356 is a data transfer language developed by the IPC to replace Gerber. It is a far more intelligent form of physical definition for PCB/PWB. The only segment of the language that seems to have developed any market support is the physical netl
