And, despite earlier setbacks associated with the use of graphite, significant advances in the overall process and in the dispersion itself has rendered the process viable for the metalization
of plated through-hole multilayer and double-sided printed circuit boards.
At the next price point, Figure 9 shows the COB in a PDA using a multilayer FR-4 PCB with uniform nickel metalization
at both soldering and wire bond sites with AlSi wire bonding process.
Generally, voiding is most often blamed on the metalization
Interconnect type failures are more frequent and marginal metalization
(electroless copper or direct metalization
) may quickly fail.
Some types of substrate require an additional etching process as part of the standard direct metalization
Simply by pre-building uncommitted wafers up to the final levels of metalization
, a product team can safely trim weeks off its fab cycle time.
The package's lead-free backside metalization
provides excellent thermal dissipation as well as visual evidence of solder reflow.
These new silicon carbide active die use a novel metalization
that requires an alternative attachment approach other than what is normally done with either conventional lead or lead free solder.
production is projected to be 22,000 tons.
A new flatbed screen-printing ink for a wide variety of plastic substrates produces mirror effects as an economical alternative to foil blocking and film metalization
Is this a true ICD, caused by problems with the metalization
Construction materials include a ceramic body, layered electrodes, silver metalization
, nickel plating and solder outer plating.
