Tape and Reel Information

Carrier tape basic dimensions are based on EIA481. The pocket is designed to hold the part for shipping and loading

onto SMT manufacturing equipment, while protecting the body and the solder terminals from damaging stresses. The

individual pocket design can vary from vendor to vendor, but width and pitch will be consistent.

Carrier tape is wound or placed onto a shipping reel either 330 mm (13 inches) in diameter or 178 mm (7 inches) in

diameter. The center hub design is large enough to ensure the radius formed by the carrier tape around it does not put

unnecessary stress on the parts.

Prior to shipping, moisture sensitive parts (MSL level 2a-5a) are baked and placed into the pockets of the carrier tape. A

cover tape is sealed over the top of the entire length of the carrier tape. The reel is sealed in a moisture barrier, ESD bag,

which is placed in a cardboard shipping box. It is important to note that unused moisture sensitive parts need to be

resealed in the moisture barrier bag. If the reels exceed the exposure limit and need to be rebaked, most carrier tape and

shipping reels are not rated as bakeable at 125°C. If baking is required, devices may be baked according to section 4,

table 4-1, column 8 of Joint Industry Standard IPC/JEDEC J-STD-033A.

The following table provides useful information for carrier tape and reels used for shipping the devices described in this

document.
