ST-QFN-20-4X4-05 QFN 20-Pin, 4mm x 4mm, 0.5mm Pitch, SMD to DIP Adapter – 3 Pack Converts a QFN 20-Pin SMD part to a DIP form factorHigh quality PCB can withstand re-workEnables SMD parts to be used with a breadboard or perfboard0.1″ pitch holes for standard headersItem sold in packs of 3 boards Specifications DIP Pitch0.1″ SMD PackageQFN-20 SMD Size4mm x 4mm SMD Pitch0.5mm Surface FinishENIGTemperature Rating-30°C to +100°C This SMD to DIP breakout board enables the easy conversion of a surface mount package to a DIP form factor. This adapter makes prototyping with surface mount parts fast and easy. Through-holes with a standard 0.1″ pitch allow the board to work with common headers and enable SMD parts to be used in breadboards and perfboards. This board has an ENIG surface finish and is made of high quality FR4 which can withstand high temperature soldering and re-work. Besides the standard pins, this board also breaks out the bottom pad of a QFN part. This pad is connected to one through-hole on each side of the board labeled «PAD», it is also routed to a centered through-hole for quick access. The QFN bottom pad is connected through to the back side of the adapter to make soldering easier. Mechanical Drawings Electrical Connections Each pin of the QFN part is electrically connected to one of the through-hole connections on the SMD to DIP adapter board. The bottom pad of the QFN part is also connected to one through hole on each side of the board. Custom Designs Can’t find what you need?
