NBB-300 RF Micro Devices, NBB-300 Datasheet - Page 7

• Manufacturer Part Number: NBB-300
• Description: CASCADABLE BROADBAND GaAs MMIC AMPLIFIER
• Manufacturer: RF Micro Devices

Carrier tape basic dimensions are based on EIA 481. 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 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 with the
appropriate units of desiccant and a humidity indicator card, 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-033.
Table 1 provides useful information for carrier tape and reels used for shipping the devices described in this document.
