Grayhill DIP Switch Processing Information
The information provided within is intended as processing guidelines for the assembly, soldering, cleaning, and use of Grayhill DIP switches. This
information supersedes any other process information that is available in Grayhill Inc. catalogs or data sheets as related to Grayhill Inc. standard
DIP switch products. Please contact Grayhill Inc. for any questions related to the information in this document.
Mounting
Unless otherwise noted, Grayhill DIP switches are shipped with slides or rockers in the ON position and rotary DIP switches are shipped with the
actuators in the 0 position. It is recommended that they be solder processed in those positions to ensure proper performance without issue.
Soldering
WAVE SOLDER: Switches that can be processed using wave solder equipment (thru hole soldering) are as follows:
temperature is 260°C. max. for 5 seconds max. (0.063” thick PCB). Exposure to flux should be kept to a
minimum.
Manual soldering guidelines (for thru hole switches): Soldering temperature is 350C for soldering iron tip with 3 seconds maximum of dwell time.
REFLOW SOLDER:
Switches that can be processed using reflow process equipment are as follows:
Grayhill Series 76HP, 78HF, 78HJ, 90B, 90HB, 94H, 94R, 97C, and 97R
Reflow soldering guidelines: Soldering temperature is 260C max. for 5 seconds, with a maximum of two reflow cycles at the maximum
conditions. Switches should be allowed to cool for 3 to 5 minutes between reflow cycles. Reflow soldering should not be done to any Grayhill
DIP switch
products not listed directly above as the exposure to higher surface temperatures could cause permanent deformation of the plastic
materials.
Recommended Maximum Soldering Conditions:
Reflow Soldering
Profile:
(260°C
Peak Temperature)
PCB Cleaning
In-line DIP switches that are tape sealed can be processed using certain washing processes as described below. Tape sealed switches can typically
be identified by a suffix of ST or PT that follows after the series, switch style, and number of position identifiers (i.e., 76SB08ST). Non-tape sealed
switches should not be subjected to any washing processes as they can introduce contaminants into the contact area of the switches. Rotary DIP
products (94H & 94R) are internally sealed and can be processed the same as tape sealed products.
Tape sealed and rotary DIP switch products are qualified for immersion cleaning processes using alcohol or detergent based cleaning solvents at
temperatures up to 140°F. maximum. Tape seal products must have the tape seal undisturbed until after any cleaning process. Cleaning processes
that use ultrasonic agitation or that use pressurized sprays can defeat the tape and / or internal seals and allow contamination of the switches. They
are not recommended for use on inline or rotary DIP products. Switches should not be washed directly after a soldering process. There should be
a delay of at least three minutes to allow adequate time for cooling after soldering.
Tape seal integrity: Inline DIP products that are tape sealed are tested to meet and pass a gross leak test using 125°C Fluorinert for 20 seconds
minimum. Reference MIL-202, Method 112.
Tape seal material:
76,78: Polyester film, rated to 170°F. maximum temperature
90: Polyimide film, rated to 260°C. maximum temperature

DIP Switch Options and Accessories
OPTIONS
Position Identification Line Option
For Series 76RSB, 76RSC, 76RSD, & 90B
A line can be added to the recessed rocker or
Series 90 slide actuator to provide positive
identification of the actuator position. To order,
add L as a final suffix to the part number. For
example, 76RSB08 becomes 76RSB08L; and,
90B08S becomes 90B08SL.
Available from a local Grayhill Distributor.
Other Switch Markings
For Series 76, 78, & 90
We can mark your part number or other wording
on the switch, often at no charge. For some
markings there will be a nominal charge for
tooling plus a set-up charge. In addition, there
is a marking charge per side per switch. Add it
to the unit price and discount it accordingly.
To order, contact Grayhill.
