Shrink small-outline package (SSOP) chips have "gull wing" leads protruding from the two long sides, and a lead spacing of 0.65 mm (0.0256 inches) or 0.635 mm (0.025 inches ). [4] 0.5 mm lead spacing is less common, but not rare. The body size of a SOP was compressed and the lead pitch tightened to obtain a smaller version SOP.
Bare die supplied without a package. It is mounted directly to the PCB using bonding wires and covered with a blob of black Epoxy. [22] Also used for LEDs. In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a mold containing the LED(s) and cured. The mold forms part of the package. COF: Chip ...
Some TSSOP packages have an exposed pad. This is a rectangular metal pad on the bottom side of the package. The exposed pad will be soldered on the PCB to transfer heat from the package to the PCB. In most applications, the exposed pad is connected to ground. [2]
[citation needed] The pad is soldered to the PCB to transfer heat from the package to the PCB. ... (SSOP) Thin-shrink small outline package (TSSOP) See also
The integrated circuit package must resist physical breakage, keep out moisture, and also provide effective heat dissipation from the chip. Moreover, for RF applications, the package is commonly required to shield electromagnetic interference, that may either degrade the circuit performance or adversely affect neighboring circuits.
Perimeter lands on the package bottom provide electrical connections to the PCB. [1] Flat no-lead packages usually, but not always, include an exposed thermally conductive pad to improve heat transfer out of the IC (into the PCB). Heat transfer can be further facilitated by metal vias in the thermal pad. [2]
The size of the Mini Small Outline Package is only 3mm × 3mm for the 8 and 10 pin versions [1] and 3mm × 4mm for the 12 and 16 pin version. [2] [3] The small package offers a small footprint, short wires for improved electrical connections, and good moisture reliability. [1]
A printed circuit board (PCB), also called printed wiring board (PWB), is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive ...
