The Embossed Tape "W4P1" has a reduced tape width and pitch size compared to W8P2 paper tape of the same chip size, providing for efficient use of tape area. This drastically reduces storage/stock space for chip components.
The narrower tape width of the W4P1 tape allows for thinner reels.
This saves on parts feeder space per modular unit of the chip mounter and increases varieties of chip components to be mounted, making mounting more flexible for production of various models in varying quantities.
