Having problem with a 2X50 SCKT Strip PTH component(fine pitch) bridging on the wave. The PCB runs in wave pallets. Just wanting to know what successful findings have been done to eliminate bridging? Pallet angles? Copper or titanium inserts? Air kni

Bridging Causes: Insufficient flux, Excessive pre-heat, High conveyor speed, Solder contamination Look here: * http://www.smtnet.com/library/files/upload/Reflow%20Wave%20Poster.pdf * http://smt.pennnet.com/Articles/Article_Display.cfm?Section=Archi

Hi, If you need to get a humidity target, the best way is to run the air conditioning plant very cold, which will drop the moisture out of the air, and then you can reheat to the required temp, and install humidifiers to re humidify the air to the r

Hi! I am in SMT manufacturing & was wondring if anyone can recommend some good reference books. Dave F, I had come across your recommended list of books on the SMT in Focus website. However this website has now been closed & was wondering if there i

Vladimir, Phil J is right. Tantalum�s moisture vapor outgassing is the root of the problem you are searching for. Internal pressure of entrapped moisture becomes very high in reflow zone. Vapor jet shifts your components and affects BGA�s bumps. Bak

We currently build a product that uses RS485. ICT is geared very well at testing serial channels, as long as there is a way to synchronize the transmit and receive lines. But in the case of a simply RS232/485 protocol, simply doing a loopback test

Is there a standard (IPC, JEDEC, JEITA, etc) covering the tolerances on percentages of Sn, Ag, and Cu in SAC305? I'd also be interested if there are standard allowable amounts of other contaminants. I couldn't turn up anything in a search of the IP

appears to be incomplete reflow on a couple of balls or they were moved during a cooldown. it also seems as though there is a deviation in ball size due to inconsistant paste application possibly. I would stop applying paste and just reflow that pa

won;t recommend a paste since I propose that you do not use but here is a flux I have had great success with Indium tacflux 20B IPN 84283 No clean flux, Use this alone without paste and your BGAs will work!! What was your package temp during th
