Regardless of the design technology of the board, we use shop floor management software that: * Calculates the period that it takes to assemble a job. Obviously, we enter product-manufacturing information [ie, BOM, material receipt dates, process fl

People like flat surfaces for placing and reflowing certain components, like fine pitch devices. Some board suppliers can supply HASL that is flat and well controlled from an amount of material stand-point. Unlike OSP, HASL has a wonderful shelf-li

Much of the ability to survive rework or thermal excursions is dependent upon the fabrication materials. The board qualification criteria under the 55110 was designed around 5 thermal heat cycles. Consider reworking a BGA in this context. BGA i

HALT is an approach to stimulate a failure till its existence. It is mainly used during product design and development phase. Traditional tests are mainly used to prove "no" failure but HALT is to make failure for information to improve in design of
