RoHS SMD PRODUCTS SOLDERING GUIDELINES
1. WASHING CONDITIONS
Our non hermetic SMD products are strictly non-washable as liquid cleaning solutions could penetrate the base to cap seal.
No-washing type flux with no washing is highly recommended. Please consult factory for any other process.

This profile is applicable for the following packages: S1, S2, S3, S4, S5, S7, S8, S11, S13, and S15
Additional recommendations:
do not vibrate during reflow soldering
do not reflow solder on back side
Only one reflow is allowed
solder adhesion may vary depending on the motherboard’s thermal capacity and other factors
Hand soldering (not recommended):
Maximum temperature: 300°C/5 sec, fine tipped soldering iron
