A little more detail on our application: It is a large fixture (approx. 15" x 18") that spans the chain fingers in the reflow. It has several cut-outs and reductions in thickness to allow for better heat distribution. It worked well/stayed flat fo

I'm looking for some information on soldering irons being used in my no-lead process. Specifically, my floor seem to be burning out tips at an alarming rate, when soldering lead-free assemblies. Today, I had one woman burn out a brand new tip in 4

The process that burnt the tips up yesterday was hand soldering/touch up of lead-free assemblies. Not even assembly, but just touching up boards that we've soldered on a solder pot...which will lead to another question. We're using SAC 305 WS482 3

ok, sorry ,750 was deg F and which I said 350~400 were deg C, I got a mistake. As I know, we use 660~720 deg F to do reworking for lead free solders such as SAC series and SnCu0.7 series solder to protect irons and components on boards. when temp.

*We've tried the WSP80s for leadfree, also SAC. Problem with these was when they are not being used, they keep their temp and oxidate like hell. Second problem is as Russ states, the sensor is not in the tip, therefore to get the same heat in the t

800 degrees? Ouch! I find that every company that I do training for has at least one person that likes to go through one tip a day. The solution is tip tinning. Tell your operators to wipe the tip on a damp sponge often. Do not buy your sponges

Interesting. We are also facing this problem due to; once in a while a matrix tray is mishandled by the operators and as a result those very, very expensive components falls to the floor and the columns got bent. We manage somethime to "straighten th

Hello bpeach, We purchased a Mirtec for our first AOI machine after a side by side comparison of three different manufacturers. The Mirtec proved to be far superior to the others that we had looked at. Initially, the intention of the AOI was to prov

What type of hardware are you looking for? Nuts and bolts? Custom machined/stamped parts? In general, stainless steel is usually considered RoHS, but more expensive. However, medical equipment usually uses things like stainless steel. However, som

Hi all, What are the pro's and cons of pasting ahead? The definition of pasting ahead for this question is the act of pasting 10 or 15 pc boards and then running then repeat. I do not like this philosophy. I'd prefer to paste, run, reflow then
