Soldering Process Recommendation Guide
The majority of customers utilizing miniature or subminiature switches in the industry today have a great concern
about the switches' capabilities during their soldering and
cleaning cycles. This concern centers around the introduction
of contaminates into the switch contact area which could
cause the switch to experience various failure modes either
immediately or during the life cycle of the switches' usage.
These failure modes can show in a number of manners.
The following are just a few examples: high contact
resistance, open contacts, low dielectric strength breakdown,
and high actuation forces causing use-related applications to
malfunction. Since most fluxes become active the introduction
of the high temperatures used in all soldering techniques, the
switch must either prevent these fluxes from entering into its
contact area or allow cleaning techniques to carry flux
particles out. It must be understood that switch contamination
can occur during any procedure: from hand soldering to the
new age Surface Mount systems using vapor phase, I.R., or
Convection chambers for solder reflow.
We at Augat/Alcoswitch offer a wide range of switches to
handle any soldering operations. However, certain soldering
conditions will not apply to all switches. The following
conditions and charts should help assist you in the soldering of
our switches in your application. If you need additional
information, feel free to contact the factory.
SOLDERING TYPES
A. WAVE SOLDERING
Top & Bottom board preheat: 200°F (93°C) for approximately 3 to 4 minutes.
Solder Temperature & Dwell Time: 500°F (260°C) for approximately 3 to 5 seconds.
B. HAND SOLDERING
1. 500°F-600°F (260°C-316°C) Utilizing a controlled 40 watt iron for 3 to 5 seconds maximum.
2. 500°F (260°F) Utilizing a controlled 30 watt iron for 10 seconds maximum.
C. DIP SOLDERING
1. Solder Temperature & Dwell Time: 500°F (260°C) for 3-5 seconds maximum.
2. Mounted on PCB .060" thick - Solder Temperature & Dwell Time: 500°F (260°C) for 10 seconds maximum.
D. SURFACE MOUNT
August performs testing of their Surface Mount switches in accordance with EIA-364-56, Resistance to Soldering Heat, test
procedures 4 (Vapor Phase) and Procedure 5 (Infrared).
Extensive amount of investigation into the two Reflow soldering procedures find it impossible to provide specific guidance
for each customer application. Augat's testing is based on laboratory test conditions and in some cases, specific customer
requirements. There are a multitude of variables that can affect the soldering process, i.e., color of the material, location of
the product on the customer's board, line speed, shadowing from other components, air flow in the oven (convection) or
lack of air flow (radiant).
Consult the individual switch pages for details or consult the factory for further information.
CLEANING TYPES
A. Solvent Wash (1.1.1 Trichlorethylene, T.M.S., T.M.C.)
B. Vapor Degreasing
C. Solvent Immersion
D. Aqueous Cleaning

• Contact Gap: The distance between a stationary contact and a
moveable contact in the open position.
Slider
Shaft
• Alternate Action: See Push-Push.
• Angle of Throw: The angle or arc through which an actuator
passes during actuation. Typically used to refer to the movement
of toggle or rocker actuators. Unit of Measure: Degree.
• Antistatic: An antistatic device will withstand a specified
potential without conducting between the actuator and any
conducting element, usually the terminals or bushing. Unit of
Measure: Typical value 15-20 kilovolts DC.
• Bifurcated Contact: A wiping movable contact consisting of two
spring fingers that grip fixed contacts. Typically found in slide
switches. Self-cleaning action. See Wiping Contact.
• Bobbin Contact: A mvable contact shaped like a thread bobbin
that rolls along the stationary contacts. Found only in slide

force.
• Detent Angle: The angle or arc between detent positions in rotary
switches. Unit of Measure: Degree.
• Bounce: See Contact Bounce.

• Break First: See Break-Before-Make.
• Butt Contact: A contact mechanism in which the movable contact
makes contact with the fixed (stationary) contact without wiping
motion between the surfaces. Typical of toggle and pushbutton
switches. See Wiping Contact.
• Capacitive Load: A load in which the initial current on making
(closing) of the contacts is higher than the steady state current on
breaking (opening) of the contacts, the current is less than steady
state. Current leads voltage in capacitive loads. See Resistive
Load, Inductive Load, Power Factor and Inrush.

power handling capacity and longer switch life. Typical of high
power industrial switches. See Single-Break Contacts.
• Dry Circuit (Low Energy, Logic Level): An application in which
power levels do not cause arcing, melting or softening of
contacts. Typically requires gold plated contacts for reliable

mechanical parameter beyond the standard set by the applicable
end-of-life criteria. Unit of Measure: Cycles (on-off operations)
(rotations).
• Insulation Resistance: The resistance between insulated parts
measured at a specified DC voltage. Unit of Measure: Megohm.
• IP: An industrial specification used in Europe (and worldwide) to
indicate the degree of protection provided by a component
against accidental contact, penetration of solids or liquids into or
through the component. See NEMA.
• End of Life Criteria: Those specifications that a switch must
meet at the end of its specified electrical life. Typically contact
resistance and/or heat rise of contacts at full rated load at end of
life.
• Leakage Barrier: A ridge or web molded into a switch housing
between terminals or contacts to increase the surface distance
between them.
• Environmental Seal: A seal that totally encapsulates the switch or
relay providing a specified level of protection against intrusion
of solids, liquids or gases into the body of the device.
• Leakage Resistance: Dielectric Strength.
• Life: See Electrical Life: Mechanical Life.
• Fixed Contact (Stationary or Statis Contact): The non-moving
contact. Typically integral to the end of the terminal inside the
switch body.
• Logic Level: Refers to power levels typical of solid state electronic circuits (TTL, CMOS, etc.). For switch selection see Dry
Circuit.
• Flux: A material added during soldering to the metal surfaces
which on heating prevents oxidation and aids the flowing of the
solder.
• Low Energy: See Dry Circuit.
• Maintained: A position (throw) of a switch which remains
unchanged when actuation force is removed from switch
actuator. Contrast with Momentary.
• Gas-Tight Contact: A contact interface (movable to fixed
contacts) in which the forces holding the contacts together are
high enough to prevent gases from migrating between the
members. This prevents static oxidation of the contact and
subsequent intermittencies of high contact resistance. Typical
forces are 280,000 PSI and higher.
• Make-Before-Break (Shorting Contact, Make First): Movable
contact makes the next circuit before breaking the first circuit.
Typically found in slide switches. Contrast with Break-BeforeMake (MBB).
• Make First: See Make-Before-Break.
• Gold Flash: A plating of gold typically less than 10 microinches
(millionths) thick. Used only as a barrier to oxidation or
corrosion of terminals to maintain solderability.
• Heat Rise: An indirect measurement of contact resistance used by
rating agencies. The temperature rise over ambient of a contact
set carrying a prescribed current is measured to determine
whether it falls within safe limits.
• Inductive Load: A load in which the initial current on making
(closing) of the contacts is lower than the steady state. On
breaking (opening) of the contacts, the current is greater than the
steady state. Current lags voltage in inductive loads. Motors are
the most common inductive load. See Resistive Load, Capacitive
Load, Power Factor.
• Inrush: A transitory high-level of current through a contact set on
making (closing). A characteristic of capacitive and some
resistive loads. The inrush currents can be large and long enough
to cause severe degredation of the contacts. See Resistive Load,
Capacitive Load, Power Factor.
• Insert Molding: In switches and relays used to refer to terminations that are placed in the mold so that plastic is molded around
the terminations. The chief benefit is an inherent seal against the
intrusion of flux into the body of the device. Therefore no epoxy
terminal seal is required.

• Mechanical Life: The number of operations of a switch without
electrical load that does not result in a degredation of parameters
beyond the standard set by the applicable end-of-life criteria.
• Momentary (Spring Return): A momentary switch position
(throw) is held only for duration of force applied to the switch
actuator.
• Movable Contact (Dynamic Contact): The contact moved by the
switch actuator into and away from contact with a fixed contact
thus forming the electrical circuits possible for a given device.
• N.C.: See Normally Closed.
• NEMA: National Electrical Manufacturers Association. A US
Standards setting group for switch products most often applied to
switches mounted in various enclosures offering specified
degrees of protection against intrusion of liquids, dust, corrosive
elements, etc. NEMA ratings are common in industrial or
outdoor applications. See IP.
• NO: See Normally Open.
• Non-shorting: See Break-Before-Make.
