The DLCC3 package design takes full advantage of the proven high reliability pedigree of the HTCC surface mount packaging technology,

which is easily integrated for automated assembly. Semelab has taken the existing standards for ceramic surface mount package manufacture

and added additional design features to enhance thermal performance, to present a competitive alternative for high reliability applications.

SOLDER PAD LAYOUT

*

Soldering temperature should be 260°C for a

maximum of 10 seconds.

The physical dimensions for the DLCC3 ceramic package are designed

to be different from the published dimensions for the “D-5B” and “E-

MELF” outlines.

The DLCC3 design fully utilises the recommended

solder footprint for the “D-5B” / “E-MELF” Package, and as such

presents a drop in replacement for existing board designs.
