Production Overview

Plastic  Transistor Outline packaging (TO) is a principal package using TH or SMD technology. It is widely used in low cost and manual applications. NFME offers TO92,TO251(IPAK), TO252(DPAK), TO263(DDPAK), TO220 ,TO247 packages.

 

Application

Transistor Outline packages are considered one of the most established industry standard packages. TO is commonly used power supplies, converters and power motor controls, Hand-held Instruments battery powered consumer products,etc.  

 

Features

* JEDEC standard compliant or reference
* Wide choice of pad sizes to meet die size per customer lead frame design capability
* Pb-free process ready and Green Molding Compound

 

Reliability Test Standards

The test criterion is zero defect out of 77 sampling units.

JEDEC Precondition J-STD-20/JESD22-A113

Design Rule

Minimum Ink Size: 20mil (500 um) diameter or non-ink with wafer mapping

Maximum Ink Height: 1mil(25um)

Minimum Sawing street width: 2.4mil (60um)

 

Wafer Thickness: Back grinding is required if the thickness exceeds NFME spec.
