SMT GUIDELINES
The SMR device is 100% Pb-free. Therefore, Pb-free solder paste with a Pb-free re flow profile is recommended.
Do not use solder paste with active or acid-based flux. To avoid submerging the device in the solder paste, the
placement height (Z) of the device on the pick-and-place equipment should be controlled carefully. Optimally, the Z
height should be set at one-half the printed solder paste height. Maintaining board flatness (coplanarity) is important
in keeping the Z height under control.
If possible use a pick-and-place machine with a visions-alignment system for proper centering on the PCB.
For the soldering process we recommend the following:
•For optimum results the reflow oven should have nitrogen purge (we recommend 1000ppm)
•To avoid damage during assembly solder re flow attachment, follow the guidelines in IPC/JEDEC J-STD-
020D.1. The device is qualified at 260 °C re flow. The following figure shows a typical temperature profile for
Pb-free (Sn-Ag-Cu or Sn-Ag) solder and the corresponding critical re flow parameters.
•Assemble the SMR within 5 days after opening the packing
•Not assembled SMR must be dried for 500h at 40 degree Celsius; 1% r.H. before repacking in a dry pack.

HANDLING PRECAUTIONS
To avoid damage to the devices, care should be exercised during handling. Proper Electrostatic Discharge (ESD)
precautions should be observed at all stages of storage, handling, assembly, and testing.
ESD INTEGRITY
ESD Robustness HBM = +/- 1kV according to ANSI/ESDA/JEDEC JS-001 (R = 1.5kOhm, C = 100pF) for Electro-
static Discharge Sensitivity Testing, Human Body Model (HBM)-Component Level; CDM = +/- 500V according to
JEDEC JESD22-C101 Field-Induced Charged Device Model (CDM), Test Method for Electrostatic-Discharge-With-
stand Thresholds of Microelectronic Components.
MSL RATING
The device has an MSL rating of Level 1. To determine this rating, preconditioning was performed to the device
per the Pb-free solder profile defined within IPC/JEDEC J-STD-020C.
TAPE OF SMR-314/334
The SMR-314/334 will be delivered on tape with a width of 32mm.
