After moving a reflow oven to a different site, what steps do you need to perform on the machine for the machine to be certified? Jim Hall and Phil Zarrow, The Assembly Brothers, address this question and share their own experiences. Board Talk This paper describes a means of measuring the DRH of minute quantities of particulate matter (1 mg or less) found on PCBs. Production Floor Over three years, there has been an explosion of companies racing to integrate the hardware and software that will constitute a viable humanoid robot. Technology Briefing This paper covers all the long-term test results as a follow-up to an earlier publication reporting interim results and preliminary conclusions. Analysis Lab This paper details a water-soluble lead-free solder paste that has improved voiding performance and washability over previous generations of solder paste. Materials Tech The performance with one alloy under design conditions that make soldering difficult demonstrate the need to evaluate the performance differences. Production Floor This project was designed to evaluate AXI results from different machine platforms by analyzing results from similar platforms at different facilities. Analysis Lab During automatic optical inspection our chip components are shifting. This is not limited to single components and changes daily. Board Talk High-Ag, low-Ag: Which alloy fits best certain application? Here we present a report on the thermal and mechanical reliability of alloys. Materials Tech The accelerometer chip is ubiquitous in today's digital devices. Its true impact didn't become apparent until many of today's most valued applications were developed.
