we have an operator who is being prescribed to wear a bone growth stimulation system. Does anyone know if tis is ESD safe? Can he wear that on the production floor as long as he's grounded and have it stored inside his smock?

Without getting into an electrical field promoting bone growth... As long as he is grounded through heal straps and/or wrist straps, it should be fine. Although I imagine being grounded would neutralize the "Bone Grower"

Use a field meter to quantify the effect of having this bone growth stimulation equipment near ESD sensitive devices.

It must be at least a little more ESD safe than a polyester sweater. And I'm sure at least at sometime someone has worn some clothing made of plastic fibers at your place. basically find the worst thing you allow, (probably polyester sweaters) and

the guy has a borken collarbone, and this "promotes healing by inducing a weak electrical current at the fracture site." The distributor says it's ok. I kind of wonder if it really is.

Intermetallics and reflow profile

I am looking for public papers or articles on intermetallic formation as a function of reflow profile. Most solder paste vendors specify peak temperature and time above liquidus, but I am particularly interested in what happens to intermetallic grow

We would be very wary of allowing 50 uinches, because this will likely result in reduced shelf life due to intermetallic growth. As a guesstimate, at least 10 uinches of that 50 uinches, and maybe more, is already intermetallic when you receive the b

Has anyone else been experiencing this lately? We have had a rash of boards that come in properly vacuum sealed. We store them in the hot room until we are ready to build, and we get bubbles under the solder mask. We've had 4 different jobs, all di

Hello Paul, Without all of the specific details of your product I would recommend providing the BOMs and samples to a couple of vendors and have them prove their capabilities. The Siplace platform is a solid platform for your application and the ap

We are currently experiencing problems with delamination during rework/2nd op activity on lead free. I am suspecting this is a result of the use of a heat gun to rework components. My assumption is that the high heat and time in area greatly increa
