No one wants to be limited to one alternative in evaluating such equipment. Who would you suggest as viable alternatives to: * Cyber Optics in evaluating alternate suppliers for inspection equipment? * Royce Instruments in evaluating alternate sup

need IPC standards for lead free solder joint reliability tests

You're correct. There is no criteria for no-lead, but there none for SnPb, either. Solder joint strength in pull/shear will vary with lead geometry, solder volume, lead metal/metallization, the way the test is done.

Dear Colleagues Does anyone know or care to share any information as to typical torque values ( N/cm ) for components that have been placed using screen printing surface mount adhesive, using a plastic stencil ? Are there any industry set shear test

depends on what you want evaluated! you can thermal cycle the BGAs and the examine the x-sections to determine failure modes at different stages of thermal cycles. you can do a stress test and corelate the # of thermal cycles with the microstructu

In a previous job, we had torque off requirements for different sized components for our screen print adhesive (non-conductive in our case). We used a torque watch that would measure max torque, so we could test production boards, shear testing was

Can anyone point me in the direction to find some IPC standards for lead free solder joint reliablity tests, such as shear tests, pull tests, vibe tests, enviroment tests, etc. I need to know what the specs. are on all aspects of reliability and how

Looking for a reasonably priced portable device to do strength test(shear/twist)on glue cured Cap/Res. Any suggestions? Thanks

Adhesive strength specs

Electronics Forum | Wed Dec 10 11:11:04 EST 1997 | Rich Scheleski

Is there a spec for the adhesives used to hold down parts before wave soldering. What size dots are recommended and what is the maximum shear force(1LB?) tested for to ensure good adhesion. Your help is appreciated Rich Scheleski

Butt connector

I seeing connector with butt (I) lead drop off after drop test conducted. the current shear force is about 3kgf. How can this problem improved.

Gluing Quality Issue !!!

Hi Rajeshmara, Mail sent with the datasheet of the glue we use in production. Thanks for first information you provide me for the shear specifications on 1206. But can you be more precise on this point ? How did you define it ? Is anyone have more
