SynQor announces Lead-Free DC-DC Converter Production
Hudson, Mass - SynQor, the technology leader in DC-DC converters, has announced their plans to eliminate the use of lead from its products and manufacturing processes. SynQor's Lead Free initiative will be achieved in two phases to be completed by July 31, 2003. The initial phase, which was recently completed, involves a change in the printed circuit board finish. The second phase will consist of eliminating lead from the solder utilized throughout the production process. When completed SynQor will achieve a Lead Free 2 status for their entire high-efficiency DC-DC converter line, well in advance of anticipated regulatory requirements.
SynQor's Lead Free initiative closely follows the guidelines defined in IPC and EIA standards. Beginning November 1, 2002, SynQor will switch their PCB finish from Hot Air Solder leveled (HASL) Sn/Pb to Electroless Nickel Immersion Gold (ENIG) for all new and previously released products. The change to ENIG finished PCBs does not affect the form, fit or function of SynQor's DC-DC converters. SynQor will begin shipping ENIG finished product immediately to customers as older inventories become depleted.
The second phase of SynQor's Lead Free initiative will involve the use of a lead-free solder paste, consisting of Sn96.5/Ag3.0/Cu0.5, used in the assembly of its converters. In addition, SynQor will change the composition of the input/output pins from Brass to Te/Cu while eliminating lead from the pin finish. These process and material changes will have no impact on the form, fit and function of SynQor's converters. SynQor has also confirmed through stringent design, testing and qualification that there are no adverse effects on product reliability as a result of the migration to a lead-free solder paste. All lead-free converters will meet solder re-flow requirements of 260oC for 90 seconds. Careful study was performed to assure that SynQor products will properly re-flow in OEM customer SMT environments with no effects on placement or solder strength of individual components. However, due to the nature of this process change, some customers require up to 9 months of advance notification, deferring the completion of SynQor's Lead Free initiative until July 2003.
SynQor's move to Lead Free 2 status marks a significant step towards the goal of complete elimination of hazardous lead from their assembled product. SynQor must now work with discrete component manufacturers to eliminate lead at the component level (Lead Free 3), which is used in component finishes and terminations.
"The transition to lead-free DC-DC converters is a major concern for our customers," says Dr. Martin Schlecht, SynQor's CEO. "SynQor has shown leadership in this area by studying this issue in depth and making the changes necessary for a totally lead-free product."
SynQor completed phase one of its Lead Free initiative (ENIG PCB finish) on November 1, 2002. Phase two (lead-free solder paste and I/O pins) will be completed by July 31, 2003 and will be communicated through a separate Product Change Notification.
