OVERVIEW
BergStik
®
2.54mm unshrouded headers are available in
surface-mount (SMT), through-hole (THT), press-fit, stacking
and pin-in-paste (PIP) versions. Designed in single and double
row, they are available in straight or right angle options, from
2 to 72 positions.
Featuring a “breakaway” design, each connector can be cut or
broken to length to suit the application profile. The maximum
current rating is 3A per contact.

UNSHROUDED HEADERS
FOR PIN-IN-PASTE PROCESSES
Pin-in-Paste (PIP) technology allows the use of THT products in SMT manufacturing processes. THT connectors are automatically or
manually soldered to PCB, and soldered in the same operation as the SMT connectors. Mechanical strength is retained through THT leads.
This process is critical for applications in industrial and automotive markets.
PRODUCT
PLASTIC MATERIAL
BergStik

PIP headers are moulded in high temperature thermoplastic. The headers are able to withstand exposure to 260°C peak
temperature for 30 seconds maximum in a convection, infrared or vapor phase reflow oven.
HOUSING DESIGN
A special housing has been developed for the double row straight product. A row of higher standoffs has been placed in the longitudinal
center axis, between both rows of pins for a good solder paste deposit around the pin. Please follow the stencil design guidelines TA-894
and TA-897 on the following page in order to avoid solder paste deposit under the standoffs.

APPLICATION
FCI’s application guideline helps to achieve optimum performance for BergStik
®
PIP process.
STENCIL DESIGN
The stencil design is crucial for a good solder joint. It determines
the amount of paste and the position of the paste print on the
board. Each PCB hole has its own stencil aperture with enough
spacing in between to allow separate solder deposits. This prevents
solder robbing from one hole to another and ensures the correct
amount of solder paste for each hole. The print position is placed
asymmetrical to optimize the flow of molten solder paste.
PASTE APPLICATION
The amount of paste for each hole depends on the soldering process
parameters and the degree of hole filling. It is recommended to
apply the squeegee at a 45° angle. You can use a smaller angle for an
even greater degree of hole filling. The squeegee moves in parallel
with the shorter sides of the stencil apertures.
BOARD LAYOUT
Please use a hole of 1.00 +/– 0.05 mm for an optimum paste deposit.
For automatic pick-and place, lean towards the upper end of the
tolerance. Refer to TA-894 for further information.
