Soldering Conditions
Following figure shows temperature profile when reflow soldering.
・Cleaning after reflow soldering should not be applied.
・Flow soldering should not be applied.
・Please contact us when using other reflow profile except following reflow profile.
(1) Cleaning after reflow soldering should not be applied.
Optical filter of sensor should not be soiled because it may cause failure or malfunction.
(2) Please follow soldering conditions described in the specification. This product can permanently stop operating if the
piezoelectric(pyroelectric) characteristic is decreased due to excessive heating.
3.Caution (Mounting)
(IRA Series)
(1) Soldering
(a) Hand soldering should be applied.
(b) Soldering should be done quickly as following.
(c) Soldering flux should be rosin flux and not contain more than 0.2wt% chlorine.
Soldering flux should be removed after soldering.
(2) Cleaning
Soldering flux should be removed after soldering.
Soldering flux may cause malfunction or degradation of character unless sufficiently cleaned.
