Mounting Instructions for Package for Lead-free solder
Mounting Condition
For soldering, Lead-free solder (Sn-3.0Ag-0.5Cu)*1 or equivalent shall be used.
1. The example solder is a tin-rich alloy with 3.0% silver and 0.5% copper, often called Sn 96 for its
approximate Tin content.
2. A rosin type flux with chlorine content of 0.2% or less shall be used. The rosin flux with low halogen
content is recommended. When soldering, use the following time/ temperature profile with any of the
methods listed for acceptable solder joints.
3. Make sure the devices have been properly prepared with flux prior soldering.
*Reflow soldering method (Infrared reflow / Heat circulation reflow / Hot plate reflow);
Limit solder to 3 reflow cycles because resin is used in the modules manufacturing process.
Excessive reflow will effect the resin resulting in a potential failure or latent defect.
The recommended reflow temperature profile is shown below. The temperature of the reflow profile must be
measured at the device lead.
Reflow temperature profile and condition:
(1). Temperature rise: 3 deg-C/seconds.
(2). Preheating: 150 – 200 deg-C, 60 - 180seconds.
(3). Main heating: 220 deg-C, 60 seconds max.
(4). Main heating: 260 deg-C max., more than 250 deg-C, 20 - 40 seconds max.
* Measurement point: Device Heat-sink (Source Pin).
1.
The above-recommended conditions were confirmed using the manufacturer’s equipment and materials.
However, when soldering these products, the soldering condition should be verified by customer using their
own particular equipment and materials.
Cleaning
Avoid washing of the device after soldering by reflow method due to the risk of liquid absorption by the resin
used in this part.

Humidity Lifetime for ELMxxxx-4PST
The following graph shows the effect of moisture on lifetime (moisture resistance) for the
ELMxxxx-4PST. Each graph indicates the MTTF and failure rate prediction (Confidential Level =
90 %) which calculated from the results of highly accelerated temperature and humidity stress test
(HAST).
Representative of device type: ELM7179-4PST
Subject of device type : ELMxxxx-4PST
Field environmental conditions for operation
If the ELMxxxx-4PST is installed in a non-hermetic environment, please refer to the following
recommendations and notes for design with, and assembly and use of our products.
Note 1. When drain current cuts off, it should be cut off by drain bias, and not cut off by gate bias
only. The humidity lifetime becomes shorter in case of the gate-only cut off operation due
to electric field strength interacting with humidity.
Note 2. ELMxxxx-4PST should be used under the environment conditions of no dew
condensation. These plots do not apply in the case of liquid absorbed into the resin,
whether applied to the part in assembly or as condensate in the application.
