Ultrathin bare die chips were soldered using a novel soldering technology. Using homogeneous flash light generated by high-power xenon flash lamp the dummy components and the bare die NFC chips were successfully soldered to copper tracks on polyimide (PI) and polyethylene terephthalate (PET) flex foils by using industry standard Sn-Ag-Cu lead free alloys. Due to the selectivity of light absorption, a limited temperature increase was observed in the PET substrates while the chip and copper tracks were rapidly heated to a temperatures above the solder melting temperature. This allowed to successfully soldered components onto the delicate polyethylene foil substrates using lead-free alloys with liquidus temperatures above 200 °C. It was shown that by preheating components above the decomposition temperature of solder paste flux with a set of short low intensity pulses the processing window could be significantly extended compared to the process with direct illumination of chips with high intensity flash pulse. Furthermore, it was demonstrated that with localized tuning of pulse intensity components having different heat capacity could be simultaneously soldered using a single flash pulse.

Isola Group has launched a technology-licensing program to mitigate conductive anodic filamentation (CAF) problems in the fabrication of PCBs. This proprietary manufacturing technology, which is offered by ISOLA USA Corp. "Isola USA", reduces the number of voids in resin-impregnated dielectrics, which is a major source of CAF failures.

The printed circuit board, or PCB, is responsible for connecting all the components with each other in your electronic assembly. Making just one tiny error in the design could lead to complete failure. PCB layout design requires ardent precision and great technological skills.
Great Lakes Engineering boasts over 20 years in chemical etching technology. In essence, this is the process of printing (photo-plotting) a pattern on a metal foil and immersing it in a precise combination of chemistry in order to eat through (etch t

Isola Group announced the introduction of Tachyon-100G laminates and prepregs, which enable line cards required to transmit 100 Gigabit Ethernet (100GbE) at data rates in excess of 25 Gb/s per channel. Tachyon-100G has identical electrical properties as its predecessor Tachyon; however, the Z-axis coefficient of thermal expansion (CTE) on Tachyon-100G is more than 30% lower than Tachyon, making it more suitable for fabricating high-layer count, 0.8 mm pitch line cards with heavy 2 oz. copper inner layers.
