We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

Grant, Why don't you try a water-base flux which is No-clean, VOC-free also? I have tried the 270WR flux from AIM with good results even on lead-free process. My $0.02, George

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le

Good day all, I wanted to get a quick poll from the folks running SAC305 in their selective soldering equipment. How are final results? How repeatable is the process, any machine related failures? pumps? nozzles? etc... I am just looking to get a

Hi, I have noticed we are getting residue on our wave pcb's and it's worse with lead free, since we changed to the flux we are using. We are currently using Avantec VOC Free flux model Ecofree 303. It looks like it's made in Malaysia. Does anyone h

CK So as I see it batch B represents a leaded process with leaded components and D is a leaded process with lead free components. Batch Components Paste B SnPb Sn62 D Lead-free Sn62 If so it is BETTER to run a lead free BGA with Sn

if the BGA has leaded balls use leaded paste if the BGA has lead free balls use lead free paste and set your oven profile to match the paste
