摘要:
Signal integrity in high-speed applications is dependent on both the underlying device performance and electronic packaging methods. The maturity of chip-on-board (COB) packaging technology using wire bonding makes it a cost beneficial option for the mass production of high-speed optical transceivers. However, wire bonding introduces parasitic inductance associated with the length of the bond wires that limits the scalability of the system for higher data throughput. A high-speed optical transceiver package according to a first proposed configuration minimizes packaging related parasitic inductance by vertically integrating components using flip-chip bonding. A high-speed optical transceiver package according to a second proposed configuration minimizes packaging related parasitic inductance with horizontal tiling of components using a chip carrier and flip-chip bonding.

The invention proposes a moulded interconnection device (MID) comprising at least one electronic component, for example a light-emitting diode (LED) light source. The electrical and mechanical connections between the light source and the conductive tracks of the MID do not have intermetallic interfaces and are more durable relative to known devices. The invention also proposes a method for assembling a light source on an MID during the production of the latter. Since all of the steps of the method can be carried out at ambient temperature, the risk of damage to the components used is diminished.

Methods for die attachment of multichip and single components including flip chips may involve printing a sintering paste on a substrate or on the back side of a die. Printing may involve stencil printing, screen printing, or a dispensing process. Paste may be printed on the back side of an entire wafer prior to dicing, or on the back side of an individual die. Sintering films may also be fabricated and transferred to a wafer, die or substrate. A post-sintering step may increase throughput.
