No N2. We could not fix a benefit for N2 in our minds. Just fold the excess bag material over to expell most air and then seal the bag. [Have you assessed the benefit of N2?] F Monette can tell you stories about little versus more pressure. If he

We trasfered a product in some time ago and they were using erasers to hold down parts. Some parts will move around during wave and some parts just need to be positioned correctly after wave so hold downs are required. I personaly have never used a b

I have used these bean bags for several years now. They work great for holding down odd formed components during the wave process. I use the cotton ESD smock material and cut out what ever size I need. Works Great!.

The rice and soup mix illustrate the point that you probably should NOT be using the lead shot mentioned in the initial post on this thread. The oxide powder on the lead shot could work its way to the surface of the "bag", get onto troops' hands, an

Just want to know if it is ok to leave parts in the bag with an open end. I just hate for the operators to start leaving parts in the mcdry with just the tray. I could see them damaging them, label incorrectly or mixing them up. Just want to know

Good morning James, It depends on MSD class. Refer to J-STD-033. When you open dry bag shelf life starts. You have to mount all devices before maximum allowable shelf life time exceeds. Storing in dry cabinet capable maintaining RH

Moisture barrier bags are polymer coated foil so are nearly gas impermeable. There's always some coating left at the weld (or it wouldn't stick) so they're not completely sealed but that's as good as it gets. Usually people use the vacuum to remove

We are going to be changing the layout of our production area and we wanted to rent or buy some air bags / air casters to help us move some of the equipment around. Does anyone know where we could rent these? Or buy? Also does anyone have any other

Referring to IPC/JEDEC J-STD-033B.1 section 3.3.2.2 'The amount of desiccant used, per moisture barrier bag, shall be based on the bag surface area and WVTR in order to limit the interior relative humidity in the MBB to less than 10% at 25°C.' So wha

Does anyone have a good answer to lifted components? I read on this site (old thread) that someone designed bean bags to set on top of a PCB to keep the components down on the board. I know that seems like a short cut to eliminate lifted components
