Bare Die Attach

For applications with the greatest space restrictions, we have a long history of working with micro-assemblies utilizing flip chips and bare die attached wire bonded COB components.

Advanced interconnect via wire-bonding is a core competency of our company. utilizing gold (Au) or aluminum (Al) ultrasonic wedge bonding, our interconnect expertise with COB (chip-on-board) can be an integral part of meeting your complete assembly needs that include SMT, Through Hole and Imbedded components.

We helped pioneer Chip On Board (COB) die on conventional PC board substrate in the 1970's. With the advent of surface mount technology passive components in small plastic packages became available and cost effective. COB rivals, and in many applications surpasses, the density of ceramic substrates since components can be economically placed on both sides of the board.

COB technology (bare silicon die) wire bonded directly to a printed circuit board and epoxy encapsulated can provide an economical approach to obtaining very high density circuit packaging. Many trade offs enable the most cost effective small package. The cost factors are: component cost, type of PC board substrate (factoring in temperature range, ruggedness, flexibility etc.), mix of die and passive components, and use of both sides of the board (reduction in total PC board material used).

We are capable of producing circuits utilizing the three predominant technologies of COB, SMT and through hole and can assist with all phases of production from design through final assembly.

We can be your partner building your COB assemblies.
