NEVALO* Interconnect System 114-13290
21 DEC 10 Rev A
All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters. Unless
otherwise specified, dimensions have a tolerance of ±0.20 and angles have a tolerance of ±2°. Figures and illustrations
are for identification only and are not drawn to scale.
1. INTRODUCTION
The NEVALO Interconnect System is designed to be a complete LED lighting interconnect solution. The
NEVALO surface mount clip mates to the Feed-Thru, Straight, and Right-Angle connector s which make a card
edge connection to the printed circui t (pc) board pads. These connectors are insulation displacement contact
(IDC) terminated to the NEVALO ribbon cable and a terminator connector is placed on the free end to create a
series circuit between all connectors and the driver.
When correspondin g with Tyco Electronics Personnel, use th e terminolo gy provided on this sp ecification to help
facilitate your inquiry for information. Basic terms and features of receptacles are provided in Figure 1.

3. REQUIREMENTS
3.1. Safety
Do not sta ck product shipping containers so high that the containers buckle or deform.
3.2. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the receptacle
connector material.
B. Shelf Life
The connectors should remain in the shipping containers until ready for use to prevent deformation to the
connectors. The connectors should be used on a first in, first out basis to avoid storage contamination.
C. Chemical Exposure
Do not store connectors near any chemicals listed below as they may cause stress corrosion cracking in the
contacts.
Alkalies Ammonia Citrates Phosphates Citrates Sulfur Compounds
Amines Carbonates Nitrites Sulfur Nitrites Tartrates
3.3. Materials
The NEVALO housings are made from glass-filled PBT, while the IDC cont acts are ma de from copper alloy with
tin plate over nickel.
3.4. Limitations
The operating temperature range for the NEVALO Interconnect System is -20° to 105°C [-4° to 221°F].
3.5. Special Characteristics
NEVALO Interconnects are availab le in four colors. Housings have a molded keying feature th at corresponds to
keying features on the mating part (clip, driver, etc.) to prevent over/under powering of light modules. See
Figure 1.

3.6. Cable Preparation
The IDC contacts in the NEVALO Interconnects are designed to accept NEVALO ribbon cable stranded tinned
copper conductors. An initial cut needs to be made using a guillotine-type cutting tool. See Figure 2. Contact
your Ty co Elec tr on ics Re pr es en tative for cur re nt t ool recommendations for cutting and notchin g of cables.
A notching procedure is required when a NEVALO Feed-Thru connector is used. Use cable notching tool 2119990-1 to
ensure proper notch size and length. Contact the Product Information Center number at the bottom of page 1 for specific
information on this process or refer to hand tool instruction sheet.
Care must be taken when aligning cable prior to termination to maintain parallelism between the end of the cable an d the
inner wall of the connector.
Figure 2
Feed-Thru connectors should not be placed closer than 25 mm [1 in.] apart (centerline-to-centerline) due to tooling
constraints. Printed Circuit Board width may effect minimum spacing.
3.7. Product Selection
All NEVALO Interconnects should b e us ed with cor respond ing color ed ri bbon ca ble, l i ght modu les, an d drivers.
Right/left, up/down orientation corresponds to connector orientation relative to NEVALO ribbon cable stripe.
Figure 3 shows proper connector orientation.

3.8. PC Board
A. Material and Thickness
The pc board material shall be metal clad. There is no required thickness for the pc board.
B. Tolerance
Maximum allowable bow of the pc board shall be 0.05 mm over the length of the connector.
C. Pads
The pc board circuit pads must be solderable in accordance with Test Specification 109-11.
D. Layout
The pc board layout must be designed using the dimensions provided on the customer d rawing for the
specific connector. Reference sample of the recommended pc board layout is shown in Figure 4.
Figure 4
3.9. Soldering
Observe guidelines and procedures when soldering contact s. Solder, clean, and dry all leads to contacts
according to the following. The connectors should be soldered using vapor phase reflow (VPR), double-sided,
non-focused infrared (IR), forced air convection, or equivalent soldering techniques. All solder joints should
conform to the Workmanship Specification 101-21 and IPC-S-815.
A. Flux Selection
Contacts must be fluxed prior to soldering with a mildly active, rosin base flux. Selection of the flux will
depend on the type of pc board an d other componen t s mounte d on the board. Additionally, the flux must be
compatible with the wave solder line, manufacturing, health, and safety requirements. Flux that is compati-
ble with the connectors is provided in Fig ure 5.

No flux allowable on any of the four inner pads.
B. Connectors with SMT Contacts
1. Solderability
The pc board pads must be solderable in accordance with Test Specification 109-11 (Test Method A,
non-activated rosin flux) and all other requirements for surface mount contacts specified in this document.
2. Solder Paste Characteristics
1. Alloy type shall be SAC 305; Sn 96.5/Ag 3.0/Cu 0.5.
2.Flux incorporated in the paste shall be rosin, mildly active (RMA) type.
3.Paste will be at least 80% solids by volume.
4.Mesh designation -200 to +325 (74 to 44 square micron openings, respectively).
5.Minimum viscosity of screen print shall be 5y10% cp (centipoise) .
6.Minimum viscosity of stencil print shall be 7.5y10% cp (centipoise).
3. Solder Volume
Solder volume may vary depending on solder paste composition.
Solder volume is required to be 4.27 mm3 per solder foot (calculated per 50% solid content).
4. Screen (or Stencil)
The stencil aperture shall be determined by the circuit pad size and thickness. It may be any shape as long
as it prevents solder bridg ing and maintains the given volume of solder paste.
C. Process
Connectors with surface mount contacts should be soldered using vapor phase (VPR), double-sided, non-
focused infrared reflow (I R) or equivalent soldering techniques. Due to many variables involved with the
reflow process (i.e., component density, orientation, etc.), it is recommended that trial runs be conducted
under actual manufacturing conditions to ensure product and process compatibility. These connectors will
withstand the temperature and exposure time specified in Figure 6.

The lead-free reflow profile is shown in Figure 7.

3.11. Terminated Connector Requirements
Prepared cable shall be terminated according to the procedures given in the applicable tooling instructions. See
Section 5, TOOLING, for details on tooling options and instructional materials. Figure 9 shows criteria for
acceptable terminations.
Tyco Electronics specified tooling must be used to ensure proper termination.
Figure 9
3.12. Repair/Replacement
NEVALO Interconnects are not repairable. If a connector becomes damaged, it must be cut from the ribbon
cable and replaced with a new one.
Pre-terminated cable cannot be used with a new connector. If ribbon cable insulation has been pierced, the cable must
be replaced as well.
4. QUALIFICATIONS
The NEVALO Interconnect System has not yet been sent for agency evaluation and testing.
