PTH - Reliability from Chip Carriers to Thick Printed Wiring Boards

Featured Article

Proof is in the PTH - Assuring Via Reliability from Chip Carriers to Thick Printed Wiring Boards

Endicott Interconnect Technologies

Credit/Source: Kevin T. Knadle, Virendra R. Jadhav

The reliability of Plated through holes (PTH's) is presented as "PTH life curves" which plot cycle to fail vs. temperature for the entire range of field, accelerated thermal cycling, and assembly reflow thermal exposures on a Printed Wire Board (PWB) or Laminate Chip Carrier (LCC). The curves represent years of testing with the Current Induced Thermal Cycle test (CITC) covering different resin systems, via constructions, and metal finishes. The curves reveal a number of critical factors in PTH reliability including the significant effect of Pb free reflows, resin system formulation, and copper plate chemistry on via life...

Best Video Soldering Tips

Lead-Free (SAC Alloy) PLCC Placement (2 of 2)

BEST, INC

Bob Wettermann

BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.

PCB Array Designs

Posted by SWAG

We do not recommend array sizes. PCB houses take a single board and turn it into a step/repeat that is best fit for their process = cheaper boards I suppose. We then approve this array and build programs and tooling to match. (...) What are your recommendations/ideas for improving control on this issue?...»»
