Adding Tracking/Security Numbers, Lot Numbers, and Production Dates

Rogers Corporation’s Power Electronics Solutions group is  introducing data matrix products codes on many of its metalized substrate materials, including curamik® ceramic substrates along with power modules, housings and baseplates. Data matrix codes are essentially two-dimensional matrix codes consisting of black and white square cells arranged in square or rectangular patterns as a unique form of identification. 

Identifying Substrates: Rogers can add data matrix codes (DMCs) to a wide range of metalized substrates, including direct-bonded-copper and active-metal-brazed substrates. Codes, which can be text or numeric in form and encoded by code-reading camera systems, are written on metalized surfaces by means of a thin oxide layer formed by an optical laser system; no additional material is required on the substrate. In addition to bare copper surfaces, data matrix codes can be written on nickel (Ni), nickel/gold (Ni/Au), and silver (Ag) plated surfaces. 

Standard data matrix code sizes are 2.3 × 2.3 mm and 3.0 × 3.0 mm, with other sizes available upon request. The single dot resolution is 0.164 × 0.164 mm. Positioning tolerance on a copper pad is ±0.3 mm. Using a data matrix code with 14 × 14 dots, for example, provides as many as 16 digits in a numeric code and 10 digits in an alphanumeric code. 

PES Design Support Hub Resource for Engineers: Rogers PES brings its 40+ years of experience together in a handy online resource that is available 24/7. The PES Design Support Hub features complete technical information on ROLINX busbars and curamik ceramic substrates, a library of technical papers on product design and problem solving, helpful videos on products and power distribution topics, and PES University training programs. Registration for access is quick and free. The Design Support Hub helps design engineers increase power, manage heat, and ensure the quality and reliability of their devices for optimal new product design.
