Tape-and-Reel Specification

December 1992

General Description

Tape-and-Reel is a new method for shipment of surface

mount devices. This approach simplifies the handling of

semiconductors for automated circuit board assembly sys-

tems.

A Tape-and-Reel holds hundreds-to-thousands of

surface mount devices (as compared with less than 100

devices in a rail), so that pick-and-place machines have to

be reloaded less frequently. This savings in labor will further

reduce manufacturing costs for automated circuit board as-

sembly.

ApplicationÐTotal System Saving

TL/HH/8352–32

Cost pressures today are forcing many electronics manu-

facturers to automate their production lines. Surface mount

technology plays a key role in this cost-savings trend be-

cause:

Automated manufacturers can improve their cost savings by

using Tape-and-Reel for surface mount devices. Simplified

handling results because hundreds-to-thousands of semi-

conductors are carried on a single Tape-and-Reel pack (see

the ‘‘Ordering Information’’ section for the exact quantities).

With this higher device count per reel (when compared with

less than 100 devices per rail), pick-and-place machines

have to be re-loaded less frequently and lower labor costs

result.

1. The mounting of devices on the PC board surface elimi-

nates the expense of drilling holes;

2. The use of pick-and-place machines to assemble the PC

boards greatly reduces labor costs;

3. The lighter and more compact assembled products re-

sulting from the smaller dimensions of surface mount

packages mean lower material costs.

With Tape-and-Reel, manufacturers save twiceÐonce from

using surface mount technology for automated PC board

assembly and again from less device handling during ship-

ment and machine set-up.

Production processes now permit both surface mount and

insertion mount components to be assembled on the same

PC board.

Ordering Information

When you order a surface mount semiconductor, it will be in

one of the 15 available surface mount package types (see

Appendix II for the physical dimensions of the surface

mount packages). Specifying the Tape-and-Reel method of

shipment (Note 1) means that you will receive your devices

in the following quantities per Tape-and-Reel pack:

Note 1: For small outline transistors, your order will automatically be shipped in Tape-and-Reel unless you indicate otherwise. For surface mount integrated circuits,

your order will automatically be shipped in conductive rails unless you indicate ‘‘Tape-and-Reel’’ after the device description on your purchase order.

Note 2: Your SOT-23 devices will automatically have Option 1 orientation unless you indicate ‘‘Option 2 Orientation’’ after the device description on your purchase

order (see ‘‘Tape-and-Reel Overview’’ for definition of SOT-23 orientations). In addition, your SOT-23 devices will automatically have the high-profile outline unless

you indicate ‘‘Low-Profile Outline’’ after the device description on your purchase order (see ‘‘Appendix IIÐPhysical Dimensions of Surface Mount Package’’ for

definition of SOT-23 outlines).

Example: You order 5,000 LM324M ICs shipped in Tape-

and-Reel.

All 5,000 devices have the same date code

#

You receive 2 SO-14 (Narrow) Tape-and-Reel packs,

each having 2500 LM324M ICs
