LEAD FORMING
Assembly of printed circuit boards, whether manual or automated, through-hole or
surface mount, requires components “prepped” and ready for assembly.
NuWay’s creative approach to solving assembly problems for over 30 years has
enabled us to build an extensive array of equipment and tooling for forming leads
of all kinds:
- Surface mount leads
- Through-hole to surface mount conversion
- Radial leads
- Axial leads
- TO-92 devices
- All types of components, including integrated circuits, transistors, capacitors,
resistors, diodes and LEDs
EPOXY SEALING
Aluminum Electrolytic Capacitors are widely used in electronic assemblies. Certain
harsh environments require sealing the ends of the capacitor, beyond the standard
sealing provided by the capacitor manufacturer.
NuWay meets this need by offering Epoxy End Sealing service.
NuWay’s process was specifically developed for protection of aluminum electrolytic
capacitors against solvent penetration during cleaning of printed circuit board
assemblies.
A highly engineered two-part epoxy is applied to one or both ends of the capacitor.
After baking, the epoxy forms a hard, smooth and durable seal to prevent harsh
chemicals from damaging the capacitor during cleaning.
Epoxy end sealing is recommended when printed circuit board assemblies are to be
cleaned with halogenated or chlorinated cleaning solvents. The end seals also provide
mechanical rigidity for those applications where microphonics are a concern.
NuWay offers end sealing for through-hole capacitors, both radial and axial styles.
Turnaround time is usually less than one week. Contact us for pricing and more
technical information.
BAKING & DRY PACKING
The plastic used in integrated circuits and other electronic components absorbs
a certain amount of moisture. The components may then be subjected to high
temperatures during the solder reflow process. The high temperature causes the
moisture to turn to steam, which “pops” and may cause cracking or de-lamination
of the component.
Because of this, moisture-sensitive components must be kept dry up to the time of
assembly of the PC board. If they are exposed to moisture in a humid atmosphere,
they need to be dried out again and packaged to keep them dry. NuWay offers Baking
and Dry Packing Service to meet this need.
The components are packaged in hi-temperature containers (usually trays), and
placed in an oven and baked at 125° C for 24 hours. After baking, the
components may be re-packaged into Tape and Reel, or left in their original
containers. Then the reel or tray is placed in a moisture barrier bag, along with
a desiccant and indicator card. A vacuum-sealing machine pulls out the air, flushes
the bag with nitrogen, and seals the bag. A product label is then placed on the
outside of the bag along with a “Caution—Moisture-Sensitive Devices” label.
We are often asked “Can you bake components while in tape and reel?”.
Unfortunately, the answer is “No”. The packaging materials—the reel, the carrier
tape, and the cover tape—cannot withstand the baking temperature. Instead, we will
remove the components from tape, bake them, and return them to the original
carrier tape and reels after baking.
NuWay observes the IPC/JEDEC industry standard J-STD-033A for handling
moisture-sensitive devices.
TUBE & TRAY PACKAGING
Components in Tape and Reel may need to be repackaged into trays or tubes. NuWay
stocks hundreds of trays and tubes to help meet your packaging needs.
Re-packaging is a specialty at NuWay Electronics!
NuWay also serves the needs of component manufacturers, such as metal stampers, to
provide specialized packaging solutions.
Contact us with your requirement, and we’ll do what we can to meet it promptly and
with professionalism.
