beam lead

[′bēm ‚lēd]
(electronics)
A flat thick-film lead, sometimes of gold, deposited on a semiconductor chip chemically or by evaporation, as a connecting lead for a semiconductor device or integrated circuit.

The MEDL DC 1338 mixer diodes employed in this mixter exhibited the following parameters (typical of high performance mm-wave beam lead devices): C.sub.jo = 0.04 pF (zero bias junction capacitance) R.sub.s = 7 [omega] (series resistance) n = 1.1 (ideality factor) C.sub.p = 0.04 pF (beam lead package parasitic capacitance) [phi] = 0.8 (GaAs contact potential) I.sub.s = 2.25 x 10.sup.-14 (saturation current) L.sub.p = 0 (negligible package parasitic inductance).
'Joining these dissimilar materials in a conventional way with a static laser beam leads to hot cracks and bubbles in the melt pool, which decreases the quality of the weld,' he explained.
