SMT processing notes
The
har-flex
® SMT con-
nectors meet the highest
demands in terms of their
processing capabilities.
The connectors are delivered
in a tape and reel packag-
ing optimized for
automatic
assembly machines. A
vacuum cover enables the
automatic assembly with a
vacuum nozzle.
The insulation body material is high temperature resistant, and
due to the black colour a secure camera recognition is ensured.
For a reliable SMT solder process, the termination pins are
100 % checked for coplanarity.
Process / Moisture Sensitivity
During the reflow solder process, the connector has to resist ex-
treme variations in temperature. Connectors consist in general
of both plastic and metal parts, which have a different behaviour
during the solder process. The Process Sensivity and also the
Moisture Sensivity are tested according the ECA/IPC/JEDEC
J-STD-075 specification.
Process Sensivity:
PSL means Process Sensitivity Level. PSL is a rating used to
identify a component that is solder process sensitive. Damages
of the connector after three times soldering are not permitted
(e.g. melted edges).
Moisture Sensitivity:
MSL means Moisture Sensitivity Level. MSL is a rating indicat-
ing a component’s susceptibility to damage due to absorbed
moisture during storage. Damages of the connector after stor-
age in damp heat and three times soldering are not permitted
(e.g. blisters).
The
har-flex ® connectors are rated with PSL R0 and MSL 1.
This is the maximum possible rating in both categories. The
har-flex ® connector resists three times soldering at the following
conditions without damages:
• min. 150 s beyond 217 °C (liquidus temperature, the melting
point of the solder paste)
• min. 30 s beyond classification temperature (240 °C / 245 °C
for har-flex ® )
• Temperature solder profile according to ECA/IPC/JEDEC
J-STD-075
• For MSL test, a storage of 168 hours at 85 °C and 85 % rel.
humidity was carried out
As the result, the
har-flex ® connectors are not process sensi-
tive and not moisture sensitive according to ECA/IPC/JEDEC
J-STD-075.
