Adapters Allow Use Of New Package With Old Footprint

product pic

These adapters are customized to allow one IC package to replace another no longer available. This includes interconnecting a large through board component with a small surface-mount footprint. The adapter design has been subjected to 1,000 temperature cycles from -55°C to +150°C and to vibration exceeding 40 gs with zero failures. Fine pitch, flexible leadframes are routinely available and good co-planarity is said to be assured. The product shown converts a 22-pin DIP to a 28-pin PLCC, with the option of mounting the DIP device upside down to keep the profile low. The adapter costs less than $10 each/100. There is a further charge of $1.00 if the company were to mount the chip.
