Working with Lead free and Pb Capacitors

Electronics Forum | Fri Jan 27 10:58:11 EST 2006 | mafc65

We are running our prduction (TV's)with Lead Free Solder, since 1 year ago, but we still have a lot of Electrolityc Capacitor (Thruhole and SMT)in stock that are for PB Solder. We have to use them before February-06. Do anybody know if there is a pro

The truth about lead-free and environment

I think 10% of us already knew this. I saw the boomerang coming years ago when LF was first mentioned. Did you guys see the tin whisker mention on the History Channel last night? It was on Technological Disasters (I believe). Didn�t see WML, bu

Netters, When I reflow a PCB there is a discoloration of silkscreen and mask. It appears if Profile is too hot! But I dont think so, maybe I'm wrong? 1. Kester 293 no clean 2. 2.1 C/s for 30s to 150 C 3. .5 - .7 C/s for 60s to 185 C 4. 1.5 C/s u

From technical point of view: it should not be a problem to mix Pb with Pb Free components soldered with a LF solder process. You have to take care about the max temperature allowed on your Pb components and make sure they can withstand the higher

Thanks for the tip! Do you find the boards require any cleanup after exiting the wave with the Superior 420-XF-LF?

I do recommend dedicated tips and dedicated workstations. Make sure that your tips come in with no lead in the tinning. There is a new, green heat resistant table mat that is being used in the industry to identify lead free areas. If operators see gr

Lead Free board laminates and surface finishes

Hi, We are in the process of transitioning to LF production. What are some of board materials being successfully used in production? Also, what surface finishes show promice of good results with SAC 305 solder? We are currently testing multiple boar

Superior 420-XF-LF is what we use. When we switched, it took some time of just running it through the stone before we got the optimal performance. Especially when going into the clean and dry tank on monday morning, we usually let the fluxer run for

Kester R562 and using lead free components

Electronics Forum | Fri Jul 06 12:11:34 EDT 2007 | james

We are starting to see issues with using Kester WS R562 with lead free components. The joints look grainy on almost all of the 0402'2 and other small components. Some of the solder does not solder to the terminations. These are hybrid boards which

Kester R562 and using lead free components

What's the metallization on the board? We use an immersion tin board and had to increase our profile to successfully solder.
