APPLICATIONS

The Back Contact Resistor (BCR) series single-value

back-contact resistor chip is one of the smallest chips

available.

Vishay EFI BCR resistor chips are widely used in hybrid

packages where space is limited. The bottom connection is

made by attaching the back of the chip to the substrate

either eutectic or with conductive epoxy. The single wire

bond is made to the notched pad on the top of the chip. (The

other rectangular pad on the top of the chip is a via hole, a

low-ohmic contact connecting the resistor to the bottom of

the chip.)

The BCR requires only one wire bond thus saving hybrid

space.

The BCRs are manufactured using Vishay Electro-Films

(EFI) sophisticated thin film equipment and manufacturing

technology. The BCRs are 100 % electrically tested and

visually inspected to MIL-STD-883, method 2032 class H

or K.
