Key words: PVD target, soldering, solderable
To assure fully activated flux, the solderable
surfaces (including the topside annular rings) must reach a minimum of 212[degrees]f.
This flip chip diode employs a 6 [micro]m thick, Sn63/Pb37 solderable
interface as part of the 30 [micro]m high solder bump.
PEM fasteners include broaching nuts with permanent threads for board mounting or component attachment; threaded or unthreaded standoffs for stacking or spacing and flare-mounted standoffs for greater pullout performance; threaded studs for use as solderable
connectors or as permanently mounted mechanical fasteners with external threads; and one-piece board-mount screw assemblies with captive screws for easy mounting and removal of PC boards.
Thin films of various metals are used by the microelectronics community to produce, for example, solderable
surface finishes, magnetic recording media, and copper wiring in printed circuit boards and integrated circuits.
with power rating of 70 mW Termination styles include solderable
nickel barrier, epoxy bondable and gold wire bondable.
In several instances, the devices also are wave solderable
In general, lower amounts of organic impurities in a solderable
coating result in better physical stability of the material.
The solder mask covers the outer part of the pad, so the solderable
copper surface is determined by the size of the opening in solder mask, not by the area of the copper pad.
, formable, and corrosion-resistant
2 Terminals: Solderable
Per Mil- Std -750, Method 2026 3 Epoxy: Ul 94V -0 Rate Flame Retardant.
Their vertical, through-hole mounting provides a small footprint and solderable
tabs extend from the shield for increased board stability.
Larger and wider pads can be fabricated with various techniques to yield copper and copper base metal solutions with and without enhanced solderable
Ticona notes that "These glass and mineral filled specialty grades offer very low warp characteristics, which is important for injection molded, lead-flee solderable
electrical components with ultra-thin wall thicknesses.
