QUAD L/TQFP
Product Overview
Low profile and thin quad flat package(QFP) are classified by the overall thickness(t) according to JEDEC definition, L type: 1.2< t <=1.7, T type: 1< t <=1.2. Low profile and thin QFPs are ideal for applications in lightweight and portable electronic products. ASECL's offering package can almost cover all the applications in memory, DSP and communication ICs. Due to the low electrical parasitic out of the small outline and shorter leads, low and thin QFPs are suitable for RFICs and an economical alternative to QFPs.
Exposed Pad L/TQFP
The exposed pad can be soldered to the PCB so that the heat can be driven off directly. Added to this, the soldered pad is also electrically grounded, and thus provides a smaller ground inductance. Exposed pad L/TQFP is a cost effective solution suitable for enhancing thermal and electrical performance.
