In 1999, Stig Oresjo, then of Agilent Technologies, conducted a major study of solder-joint defects on printed-circuit boards (PCBs). The study, which at the time provided the most definitive data on ...

As the core technology used in modern electronics manufacturing, surface-mount technology (SMT) assembly density is increasing, the number of pins is increasing, and the pitch is decreasing. In ...

Conversely,experienced embedded designers know to mask or tent BGA vias at thedesign and layout level. Even when this step is omitted, adesign-for-manufacture (DFM) check mapped out at the planning ...

Board manufacturers are boosting their investment in inspection, test and analytics to meet the increasingly stringent demands for reliability in safety-critical sectors like automotive. This ...

Flip chip microelectronic packaging has emerged as a cornerstone technology in modern semiconductor assembly, wherein the die is mounted upside down to the substrate to facilitate direct ...

X-ray and advanced automated techniques combine to create a capable tool for lead-free solder inspection needs. Within two years, solder used in electronics manufactured or sold in Europe must meet ...

The complexities associated with the use of solders in electronic products. What’s the alternative to solder? A long-standing adage observes that “if the only tool in your tool chest is a hammer, the ...

Solder is the conductive metal glue that one uses to stick components together. If you get the component and the PCB hot enough, and melt a little solder in the joint, it will stay put and conduct ...
