Solder Reow Recommendations
Notes:
• MF-MSMF models cannot be wave soldered or hand
soldered. Please contact Bourns for soldering
recommendations.
• All temperatures refer to topside of the package, measured
on the package body surface.
• If reow temperatures exceed the recommended prole,
devices may not meet the published specications.
• Compatible with Pb and Pb-free solder reow proles.
• Excess solder may cause a short circuit, especially during
hand soldering. Please refer to the Multifuse® Polymer PTC
Soldering Recommendation guidelines.
• Designed for single solder reow operations.

clean solder paste
(see note 1)
• single sided epoxy glass
(G10) (UL approved)
•PC board approx. 4x4x.06 in.
2. Place test units onto board 6 units/board
3. Ramp up Convection oven (see note 2) 2.5 °C ± 0.5 °/sec.
4. Preheat (TS.ces 03 ± 09C° 091 ot C° 051)
5. Time above liquidus (TL.ces 09-06C° 022)

8. Cleaning water clean profile High pressure deionized 72 °F to 160 °F As required
water 65 PSI max. (22 °C to 71 °C)
Inspect solder joint to determine if solder joint is
acceptable (i.e. exhibits wetting of joint’s surface).
Use the following criteria (ref. acceptability of printed
board assemblies, IPC-A-610):
A) Acceptable (see Figure 1)
(1) The solder connection wetting angle (solder to
component and solder to PCB termination)
does not exceed 90 °.
(2) Solder balls that do not violate minimum
electrical clearances and are attached
(soldered) to a metal surface.
B) Unacceptable (see Figure 2)
(1) Solder connection wetting angle exceeding
90 °.
(2) Incomplete reflow of solder paste.
(3) Dewetting.
If unacceptable, determine cause and correct prior to
next run.
NOTES:
1. Water soluble solder paste only above 100K.
2. Refer to ref. temperature profile. Temperature at
lead/pad junction with “K” type thermocouple.
3. Units that are board mounted for environmental
testing must see a peak temperature in the reflow
zone, as specified. This is to ensure that all test
units will see “worst case conditions”.
4. Ramp down rate to be measured from 245 °C to
150 °C.
5. Process Description 8 does not apply to open
frame trimmers.
