Leaded Packages Tape & Reel Service Offered by NPI Materials
Note: These packages peaked and are in decline. Still emerging are high power versions used in driver applications. The SOIC-08 introduced in the 1980's remains the highest volume package produced today. We've added stretched SO8 packages in support of Avago/Broadcom packages and continue to add QSOP/MSOP but the decline is evident.
