image thumb 2 1

Integrated circuit packages, the form an IC is manufactured in, are as wide and varied as a Donald Trump “alternative truth”.  Below is the big list of integrated circuit (IC) package types including the package name, package full (official) name, remarks and notes, and a picture of diagram of the electronic package.

Through-hole packages

Through-hole IC packages have leads which can be soldered onto a PCB or inserted into a breadboard slot.

SIP or SILSingle in-line packageHas one row of connecting pins often with a lead frame used as a heat sink.SIP or SIL - single in-line package
DIP (DIL or DIPP)Dual in-line packageHas two parallel rows of connecting pins – 0.1 in (2.5 mm) pin spacing, rows 0.3 in (7.6 mm) or 0.6 in (15 mm) apart. Sometimes referred to as Dipn where n=total number of pins.DIP - Dual in-line package
