    Although surface-mount, these devices require specific process for assembly. Chip-on-board (COB), a bare silicon chip, that is usually an integrated circuit, is supplied without a package (which is usually a lead frame overmolded with epoxy) and is attached, often with epoxy, directly to a circuit board.

    In 2008, High-speed mounting methods evolved through a cooperation between Reel Service Ltd. and Siemens AG in the development of a high speed mounting tape known as 'MicroTape'. By adding a tape-and-reel process into the assembly methodology , placement at high speed is possible, achieving a 99.90% pick rate and a placement rate of 21,000 cph ...

    en.wikipedia.org/wiki/Die_preparation

    Wafer mounting is a step that is performed during the die preparation of a wafer as part of the process of semiconductor fabrication. During this step, the wafer is mounted on a plastic tape that is attached to a ring. Wafer mounting is performed right before the wafer is cut into separate dies. The adhesive film upon which the wafer is mounted ...

    en.wikipedia.org/wiki/Dicing_tape

    Dicing tape can be made of PVC, polyolefin, or polyethylene backing material with an adhesive to hold the wafer or substrate in place. In some cases dicing tape will have a release liner that will be removed prior to mounting the tape to the backside of the wafers, with a variety of adhesive strengths, designed for various wafer/substrate sizes and materials.

    en.wikipedia.org/wiki/Tape-automated_bonding

    Tape-automated bonding (TAB) is a process that places bare semiconductor chips (dies) like integrated circuits onto a flexible circuit board (FPC) by attaching them to fine conductors in a polyamide or polyimide (like trade names Kapton or UPILEX) film carrier. This FPC with the die(s) (TAB inner lead bonding, ILB) can be mounted on the system ...

    Surface mount components are placed along the front (and often back) faces of the machine. Most components are supplied on paper or plastic tape, in tape reels that are loaded onto feeders mounted to the machine. Larger integrated circuits (ICs) are sometimes supplied and arranged in trays which are stacked in a compartment. More commonly used ...

    The damaged transistor shows a low-ohmic junction between gate and drain terminals. A parametric failure only shifts the device parameters and may manifest in stress testing; sometimes, the degree of damage can lower over time. Latent ESD failure modes occur in a delayed fashion and include: Insulator damage by weakening of the insulator ...
