Plastic dual-in-line packaging (PDIP) is a principal package using the pin-through-hole (PTH) technology. It is widely used in low cost and manual applications. ASE offers PDIP with lead counts ranging from 8 to 64 leads and package width from 7.62mm (300mil) to 17.78mm (700mil). For package size reduction, ASE offers two alternatives - the narrow body type, Skinny PDIP (width is 300mil, lead count is 24, 28) and the narrow lead pitch type, Shrink PDIP or SDIP (lead pitch is 1.78mm or 70mil, lead count is 32, 56, 64).


Dual-in-line packages are considered one of the more established industry standard packages. PDIP’s broad ranges of applications include logic, memory ICs, microcontrollers, and logic, power ICs used in automotive devices, consumer and communications products.
