We are performing testing for lead free connector finishes. We want to run solderability tests on a series of lead free connector plating options in a series lead free PCB's. I need some advice on the most popular lead free PCB finishes. I am aware

Hi, I am looking for service providers who can help me with determining the age in actual use of an assembled product (PCBA + plastic assembly) if the PCBA is not conformally coated. The actual use will be on car dashboards much like an action came

One of my customer had an oven made of galvanized metal. when he rised the temperature for lead free application the zinc from the alloy(blower turbine and housing,...) was melted and was removed .I offered to my customer an used oven tornado made by

I have recently been testing a new Iron that will be introduced on the market soon. The temp drop is coming in at 30c versus most other irons I have tested drop about 70c the tips are elctroplated and designed for lead free we have been very impresse

We use the JBC irons with and without the "leadfree" tips. We really have not noticed much difference between the standard and the lead free. The lead free tips do last a little longer but the tips are somewhat deformed by the extra plating. As f

Hi Wade As Steve says - are you sure that the lead is in solution? Particulate lead like solder balls is much easier to remove. The answers are going to depend on total output in gallons, maximum flow required and what has to be removed. If you're

Can anyone tell me if there is a procedure for storing raw PCB's? We currently are seeing an issue with lead free boards with dewetting. We tracked it down to one or two datecodes, but not all of the boards have dewetting. Is there a expiration da

We are testing SAC paste for thru-hole components in the 2nd reflow process. The solder joint is alright but some problem encountered in FR1 or CAM2 PCB after multiple times of reflow due to the temperature. We are very interested in Zn or Bi-based l

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

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.
