Package variant to be specified at order. † 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 C A B A B C mm 7.32 1.78 3.94 Inches 0.288 0.070 0.155 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 “EMELF” 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.

Part numbers are built up from Type, Package Variant, and screening level. The part numbers are extended to include the additional options as shown below. ESA Quality Level Products are based on the testing procedures specified in the generic ESCC 5000 and in the corresponding part detail specifications. Type – See Main Part Number Package Variant – See Mechanical Data Screening Level – See Screening Options (ESA / JQRS) Additional Options: Semelab’s QR216 and QR217 processing specifications (JQRS), in conjunction with the companies ISO 9001:2000 approval present a viable alternative to the American MILPRF-19500 space level processing. QR217 (Space Level Quality Conformance) is based on the quality conformance inspection requirements of MIL-PRF19500 groups A (table V), B (table VIa), C (table VII) and also ESA / ESCC 5000 (chart F4) lot validation tests. QR216 (Space Level Screening) is based on the screening requirements of MIL-PRF-19500 (table IV) and also ESA /ESCC 5000 (chart F3). JQRS parts are processed to the device data sheet and screened to QR216 with conformance testing to Q217 groups A and B in accordance with MIL-STD-750 methods and procedures. Additional conformance options are available, for example Pre-Cap Visual Inspection, Buy-Off Visit or Data Packs. These are chargeable and must be specified at the order stage (See Ordering Information). Minimum order quantities may apply. Alternative or additional customer specific conformance or screening requirements would be considered. Contact Semelab sales with enquires. MARKING DETAILS Parts can be laser marked with approximately 7 characters on two lines and always includes cathode identification. Typical marking would include part or specification number, week of seal or serial number subject to available space and legibility. Customer specific marking requirements can be arranged at the time of order.
