PHOTOFABRICATION ENGINEERING, INC. (PEI), Milford, MA (November 9, 2009) offers a full line of custom and standard step lids and flat lids for seam-weldable microelectronic packages, now available with sputtered getters for moisture absorption. Package and hybrid manufacturers may purchase lids to a given print or by specifying the package to which the lid will be welded. PEI's standard tooling list has lids to meet almost every common specification; custom lids are also available with a one-time tooling charge (which may be absorbed on large-volume orders).
The standard base material for PEI's lids is etching-grade iron-nickel-cobalt alloy, but PEI can also etch lids from other materials, including Nickel-200, stainless steel, and cold rolled steel. Plating and finishing options are also available, including gold plate, electrolytic nickel, and electroless nickel. Selective plating is also available upon request. With our large in-stock inventory of materials, PEI offers the fastest turn-around time in the industry.
PEI will design lids to exact customer dimensions and specifications to ensure a precise fit on customer packages, and will guarantee the proper fit. For 0.010 in. (0.254 mm) to 0.015 in. (0.381 mm) lids, the typical tolerance is +/- 0.003 in. (0.076 mm) on features and +/- 0.001 in (0.025 mm) on the flange. Flatness will be held to 0.002 in (0.05 mm) per inch (25.4 mm). On lids 0.020 in. (0.5 mm) or greater, typical tolerances vary due to material thickness. Whatever your tolerance requirements, PEI can meet them -- contact our sales department for details at firstname.lastname@example.org.
PEI also offers sputtered getters on all of our custom lids to absorb moisture, reinforcing our reputation as being the BEST provider of high-quality, competitively-priced lids in the market. We have an entire department devoted to the daily etching of seam-weldable microelectronic packages.
