Yes, All six new (LF ready kit) thermocouples are tested good.I would like to say boards are populated on both side back to back with two heavy PLCC's side by side just like having heatsinks and ground plane.Some Odd design.Next try will be to have a

Yes we do place "big and heavy" SMT DC/DC:s on most of our board's. Please tell us what brand it is or at least what the package look like?!? For instance we place a different numbers of "heavy" DC/DC converters (40x20mm & 45x25mm) that has the pick-

Hi, I use convection reflow and both top & bottom settings are the same. Is the part too heavy to rely on surface tension? there is an equation that can determine this (aswell as real test i.e. part falling off) We have some SIM Card holders on bot

You have already come up with what I consider the industry standard fix. Attach your weight to one of those heavy duty black paper clips and it is pretty easy to move it up as the tape runs onto the floor. I know of a lot of people doing this. Not aw

You could probably make do with two as long as you attach to the smallest part in a sparsely populated area and a large heavy part in a densely populated area to cover both ends of the spectrum. When I had a MOLE I used all 6. Now I use the 3 the ove

I think John is right. I've seen the same thing (I think, without a picture who knows)on heavy heatsink parts. But I've also seen this happen on larger parts that move right after being wave soldered. I'm talking within a second or two of being so

When running some double sided reflow boards through the Heller oven, some of the caps/ res's are falling off the bottom side of the board. I understand if the parts are too heavy they wont stay in the molten solder, but these particular parts are no

Careful when you get them! I ordered some overnight some time ago because I was too disorganized to have spares. An operator set a heavy steel vise base on top of the bag-o-bulbs while I was taking off the camera cover and crushed all the new ones.

I like the possibilities. Couple thoughts; all good equipment is solid, don't try and design a machine around modular aluminum extrusions, they're junk. At the very least use a heavy steel table with a 1/2" base and 4" square legs, they can be bou
