Introduction
Devices that surface-mount J-lead, quad flat pack (QFP), ball-grid array (BGA)-including FineLine BGATM-packaging common boards because they provide density, size, cost benefits. However, precautions, however, necessary protect these devices from mechanical damage during transportation storage. Following guidelines this application note will preserve quality Altera devices J-lead, QFP, packages ensure easier soldering. This application note discusses following topics:

Handling J-Lead Devices
protect device leads ensure proper operation, J-lead devices must handled carefully when they stored, shipped, transferred. J-lead devices should stored shipped tubes sealed with stoppers. When necessary, foam inside tubes cushioning. devices carriers should shipped only inside tubes sealed with stoppers and, necessary, with foam. Carriers static-dissipative, molded plastic shells that hold devices secure frame prevent mechanical damage device leads. These devices programmed erased inside carriers, they tolerate baking required packing. When handling devices carriers, touch device; only finger cots touch carrier.
need insert device into carrier, contact Altera® Customer Marketing (408) 544-7104. Carrier Development Socket Data Sheet more information carriers. devices without carriers, devices that have been extracted from carriers, devices should stored shipped only trays sealed with straps. When extracting devices from carrier, only Altera extraction tools, inspect orientation lead integrity devices. should extract devices place them directly into trays.

Tubes J-Lead Devices Devices Carriers
Altera-approved tubes protect J-lead devices carriers from electrostatic discharge (ESD) during transportation storage. clear tubes allow easy inspection contents' top-side markings. tube material should antistatic (with "antistatic" printed it), they should stiff enough prevent tubes from warping, cracking, developing burrs during normal handling. Follow these guidelines when transporting storing devices tubes:
Keep tubes horizontal. Keep devices "dead bug" orientation. Figure Ensure that devices overlap inside tube. When programming UV-erasable EPROM devices, only conductive tubes.

Straps Devices without Carriers
Straps secure trays prevent devices from jostling during transportation storage. hold trays together during transportation, Altera recommends using least 1/2-inch-wide polypropylene straps that withstand temperatures 130° case need bake devices before mounting. When storing devices, Altera recommends using either Velcro polypropylene straps. Velcro straps that inches length sufficiently long bind stacks trays storage. Follow these guidelines when strap trays together shipping:
only heat-sealed polypropylene straps. (Although Velcro straps hold trays together during storage, they lack strength required hold trays together during transportation.) tension strapping machine high enough prevent straps from sliding stack trays. Secure three heat-sealed polypropylene straps across width stack, placing straps indentations long sides trays. Figure Secure polypropylene strap across length tray. Remove straps with knife prevent jostling devices trays. rubber bands, masking tape, string, other similar material place Velcro polypropylene straps.

Open bags close seal possible leave enough resealing. Reseal bags after opening minimize exposure moisture. Inspect packs potential leaks seals bags. leak exists humidity-indicator card shows unacceptable humidity level (i.e., started turn pink), rebake devices. leak exists humidity-indicator card shows acceptable humidity level (i.e., blue with pink), reseal devices undamaged bag.

Distributors have additional allotment time beyond labeled floor life. hours available products with 24-hour floor life, hours available products with 168-hour one-year floor life. These time allotments allow programming repacking needed. Altera recommends following guidelines when dry-packing devices:
When transferring parts pack bags, operators should remember copy floor life expiration date accurately dry-pack labels. Bake devices strapped heat-resistant trays 125° least hours. Bake J-lead devices heat-resistant tubes 125° least hours. lack heat-resistant tubes, bake J-lead devices cookie sheet dead-bug orientation. heat-sealed bags that resistant punctures abrasion. foam covers bubble wrap around stack trays inside moisture-barrier avoid punctures. Seal bags with vacuum-operated bag-sealing machine. Relax vacuum enough prevent tube tray from puncturing bag.

Shipping J-Lead, Devices Boxes
When shipping trays tubes devices, only boxes that have passed ASD776 test shipping containers. protect against ESD, Altera recommends that boxes with internal, conductive finish. should filler material boxes cushion contents prevent trays tubes from shifting position during shipping. Boxes should contain enough filler material prevent stoppers from falling tubes when jostled. Filler material should meet following standards:
Filler materials should antistatic non-corrosive. Filler materials should crumble, flake, powder, outgas, shed. Filler materials should scratch puncture trays, tubes, dry-pack bags.
