Can anyone share with me the price you pay for LF solder paste? I have a chinese brand on hand that is purported to reflow well in air and leave shiny joints and minimal solder balls. It does not flow like lead based solder of course, nothing does.

Lets not forget about shipping costs,lead times, and bad lot recovery plan(s)on product rec'd from China. We are paying $.096 per gram (SAC405)with 4kg per wk usage. Shipping is free, stock maintained locally with 2 hr. delivery if necessary. Russ

Hi all ! I have a very simple ( maybe stupid ) question : Can we mix the lead-free components with 'Pb components' ? I mean, some component would lead-free, but it is only 5% of the whole. Will I have problems on wave and on reflow ? Thanks for hel

do you mean the parts like capacitor or solder paste/solder bar. If you mean solder paste/solder bar, yes you'll have big trouble. Why? because LF solder paste/solder bar has high melting point and different composition. However if parts like capac

Habba: Here is a thread from the fine SMTnet Archives from a couple of weeks ago, where we spoke about the topic of mixed lead-free solder with components that have lead-bearing solderability protection: http://www.smtnet.com/forums/Index.cfm?CFApp=

Armin Habba could be considering a situation where: after they convert to no-lead they receive components with lead-bearing solderability protection from their component supplier. This could happen when: * Supplier has not converted to no-lead. * O

As long as they're good. Have you guys had any free "help" from so called engineers that turned into a costly waste of time (both in resources and line down). I have heard some real horror stories from former co-workers. I haven't heard this about th

I second that one Glenn. I have had really solid support from my paste company. Our guy is Kevin with Aimsolder. He is quick to respond and very knowledgable. We used a cheaper paste a while back, but never ever got any support. I wont make that mist

Hi All Thanks for your interesting replies :) At this stage I feel that we are leaning towards a second hand DEK 265 GSX vs a new EKRA E4 or X4, and with the saving made we will get it well refurbish and add a board loader, and hopefully a proflow

The MPM's are the Yugo's. You can fix anything on it with duck tape and a rubber band. I would go with the DEK. They are user friendly and reliable. Just make sure that if you are running double-sided boards to look into good push-up pins. They have
