Are you refering to reflow soldering or wave soldering? Brian, do you have any data to support that SAC305 is more reliable than Tin-Copper-Nickel? NEMI reccomended SAC type alloys for reflow and Tin-Copper for wave. See: http://circuitsassembly.

Hello, We�ve ordered the line machinery for our TV factory. It should be ready after two to three months. We will start producing Analog CRT TVs using single sided FR2 or CEM1, thru-hole components and tin-lead wave soldering process. Knowing that

I have Immersion Ag and Immersion Sn LF boards that were waved using SAC305 alloy. I have a lot of tears/shrink voids in the waved connections. I am aware that SAC305 in wave has a propensity of shrink tears/voids due to the non eutectic property of

I�m working in Solder paste manufacturing industry and my customer has complained the void issue on BGA pad. I�m internally conducting the void test on BGA pad in my Lab. I used OSP furnish board with Sn/Pb and /or lead free component using Lead free

Dear All, We plan to setup an assembly line for our small volume production of PCBs (about couple hundred PCBs per week). The board has about 150 components (less than 30 types) and a few BGA and IC (majority is SMT, only few THT connectors). We hav

Normally someone would have replied to tell you to do a search of the archives. I've read at least 4 or 5 different threads dealing with baking out PWB's, but none were for this special material. First, have you contacted the manufacturer of the PW

What is the general consensus on automated solder paste inspection? In a previous life, when we implemented AOI equipment, we implemented it at the end of the SMT line; our reasoning was that our screen printers had adequate repeatability for our pr

This doesn't help the original poster any, but does the Quad have any sensing of what is going on in the feeder? On the pneumatic or mechanical Philips feeders, if the tape jams in the feeder for some reason, the head just keeps tapping the lever an

Hello, all, I have been having problems with bent push rods on my Philips CSM84. I have caught it a couple times when it happened, but it happens so fast I still don't know exactly what the sequence is that causes this. The push rod is clipping a

Good Morning, We are seeing an increased number of our customers that specify a Pb-Free BGA when the rest of the board assembly is SnPb. Of course when we reflow at the SnPb profiles, we don't always get a properly collapsed BGA. So we end up rewor
