1. INTRODUCTION
This specification covers the requirements for application of the PC Screw Terminal Strip. This right--angled
terminal strip is designed to be mounted on a printed circuit (pc) board and is available in 2--, 3--, and
6--positions. Other positions are possible because of the segmented housing allows separation into smaller
positions. The terminal strip will accept open spade terminals sized for M3.5 x 0.6 Phillips Screws. This
assembly will also accept stripped solid or tinned stranded wire without terminals. It will operate at 300 volts AC
maximum. Underwriters Laboratories Inc. (UL) Approved for factory wiring only.
When corresponding with Tyco Electronics Personnel, use the terminology provided in this specification to help
facilitate your inquiry for information. Basic terms and features of components are provided in Figure 1.

3. REQUIREMENTS
3.1. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the housing
material.
B. Shelf Life
The terminal strips should be used on a first in, first out basis to avoid storage contamination that could
adversely affect electrical continuity.
C. Chemical Exposure
Do not store terminal strips near any chemicals listed below.
Alkalies
Amines
Ammonia
Carbonates
Citrates
Nitrites
Phosphates Citrates
Sulfides Nitrites
Sulfur Compounds
Tartrates
3.2. Characteristics
These terminal strips use common Sems--style screw termination with an anti--backout feature. There are four
solder leads per position which are on 11.4 mm [.449 in.] centerlines. Two solder leads are “clinched” to
provide mechanical attachment to the pc board during wave soldering during the customer’s assembly
process. The terminal strip has an operating temperature range of --40 to 90C [--40 to 194F].
3.3. Materials
The housing is made from UL 94V--0 rated black 30% G.F. PBT. The screw and Sems plate are steel with
nickel plating. The solder contact is copper alloy with tin--lead over nickel underplate.
3.4. Wire Selection and Preparation
NOTE
i
If using open spade terminals, refer to Application Specification 114--2084 for contact crimp information, termination
requirements, and recommended tooling. If using stripped wire without terminals, refer to Paragraph 3.4.A and B and
see Figure 2.
A. Wire Selection
Each terminal will accept one stranded or solid copper wire, size 12 through 22. Stranded wire should be
pre--tinned before terminating. Wire insulation maximum diameters shall be 4.75 mm [.187 in.].
B. Wire Preparation
The wire strip length shall be 19.0 +3.2 mm [.75 +.12 in.].
CAUTION
DO NOT nick, scrape, or cut the wire conductor during the stripping operation. The wire shall be corrosion--free.

3.5. PC Board
A. Material and Thickness
1. Board material may be glass epoxy (FR--4, G--10).
2. The terminal strip can be installed on 1.5 mm [.060 in.] thick pc boards. Board thickness may vary
depending upon the application, however, contact tine length through the pc board becomes important
for wave soldering operations. A recommended minimum of 1.02 mm [.040 in.] of the contact solder tine
should protrude through the pc board.
Contact the Product Information Center or the Tooling Assistance Center number listed at the bottom of
page 1 for suitability of other board materials or thicknesses.
B. Tolerance
Maximum allowable bow of the pc board shall be 0.25 mm [.010 in.] over the length of the terminal strip.
C. PC Board Layout
The contact holes in the pc board must be located as shown to ensure proper placement and performance
of the terminal strip. Design the pc board using the dimensions provided in Figure 3. The layout shows the
top (component) side of the board.

C. Clinching
At least four solder legs must be clinched to maintain correct position of assembly to pc board during the
wave solder process. See Figure 4.
3.8. Soldering
Observe guidelines and procedures when soldering contacts. All solder joints should conform to those
specified in Workmanship Specification 101--21 and all other requirements specified in this document. Solder,
clean, and dry all wire leads to contacts according to the following:
A. Flux Selection
Contact 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 and other components mounted on the board. Additionally, the flux must
be compatible with the wave solder line, manufacturing, health, and safety requirements. Call Product
Information at the number at the bottom of page 1 for consideration of other types of flux. Flux that is
compatible with these terminal strips are provided in Figure 6.

Tyco Electronics Corporation
Rev E
PC Screw Terminal Strip
114- 13110
1. After the terminal has been correctly crimped to the wire, decide which circuit position is to be used.
2. Loosen the circuit position screw so that the crimped terminal may be placed under the Sems plate in
the correct position.
3. Once the crimped terminal has been positioned under the Sems plate, tighten the screw to
0.90 to 1.12 N--m [8 to 10 inch--pounds].
B. Bare Wire
1. Strip the wire to the correct length according to the dimensions given in Paragraph 3.4.B. Bend the
wire to end in a half circle (“J” shape). This is required for wire sizes 12--18 AWG and optional for wire
sizes 20--22 AWG. See Figure 10.
2. Decide which circuit position is to be used.
3. Loosen the circuit position screw to allow clearance for the wire conductors to be inserted under the
Sems plate of the circuit.
4. Insert the wire until the insulation is flush with the circuit position face.
5. Once the bare wire has been positioned in the circuit position, tighten the screw to 0.90 to 1.12 NDm
[8 to 10 inch--pounds].
NOTE: If multiple wires are used
within the same circuit, then the
wires must be of the same gauge
and twisted together. (Wire size
range 18-- 22 recommended only).
