I am doing some research on flux free/flux less SMT reflow soldering. Do you have any equipent/process recommendations? Does anybody use it for volume production and what are the constraints (finish, balls, paste, vacuum, pressure, size)? What is

I was asked to try and find us some good Lead-Free soldering Irons, I know all Irons are "LEAD FREE" I mean I need to know if anyone has any recomendations for an Iron with really good recovery time, that is higher heat capable. For a price that isn'

I have been using several PS800 soldering irons for sometime now and find them very good indeed. Tip life etc are all excellent. At the moment I am trialling the new PS900 iron, early indications go that it is even better. I also have no affilition w

Take a look at Pace and Metcal both have quick recovery irons that are good for lead free applications. Also try a preheater to warm the boards prior to solder. D. David McGee Mfg. Eng. Gaston Electronics 704-822-5031 Phone dmcgee@gastonelectronics.

The pad size is okay. I have also requested the manufacturer's recommend reflow profile. I have seen some issues with 0402 caps that we run also but for the most part solder paste does okay. I think the cap issues is stencil related. Still trying to

I think so. My customer once assembled resistors 0402 ,by Glue+wave soldering process. But PCB must be printed soldermask bridge between 0402 SMD PADs, otherwise you would encounter short problem. Sorry I don't have any comment for recommended footp

Well, since you've gotten no takers, we'll launch in to this with careful analysis and introspection, fully aware that we're likely to get 'blasted' for any number of reasons. The most critical parameters to monitor for proper wave solder machine pr

To my mind, the solder paste has clearly melted, but your HASL plating has not. This with your profile seems to suggest there's something a little weird about your PCB. However, there are probably still questions we could ask - have you successfully

Hello everyone, I'm out on market for wave soldering machine. I have been using ERSA 330 ETS for three years now, but it is quite old and I would like something newer. I'm considering ERSA N wave 330, yom 2005; and SEHO PowerWave 8440, yom 2010. Wha

You might want to try baking the LED's in an oven for 24 hours prior to build. We keep our LED's in a humidity cabinet all the time, as we have noticed poor solderability if they are left out for too long. This may be even more important when buying
