Note:
1. PCB Material; FR-4 Glass-Epoxy, h=0.30mm (or 0.10mmx3 Layers).
2. Hatched sections show the circuit patterns or the solder-masking pattern.
3. The bottom surface is a ground plane.
4. To place a ground plane at 0.3mm from the top surface is recommended.
Less distance may result in variation of the operating frequency due to stray capacitance.
Note:
Impedance of both input and output lines should be 50 ohms including land
pattern. This is the land pattern which applies t=0.2mm glass epoxy board (dielectric
constant=4.8, copper metalized on both surfaces). The stray capacitance should be
reduced as much as possible by removing the ground layer under the I/O land to secure
the isolator performance.

SOLDERING AND MOUNTING
SOLDERING
1. Reflow Soldering
Soldering must be carried out without exceeding the
approved soldering temperature and time shown within
the shaded area in Fig. 1. When soldering is repeated,
the allowed time should be taken for the accumulated time.
The standard soldering conditions are shown in Fig. 2.
2. Soldering with soldering iron
Soldering with soldering iron should be carried out according
to the following conditions.
Pre-heating
Temperature: 150°C
Time: 60 to 120 sec.
Soldering
Temperature (at the tip of the soldering iron): less than 280°C.
Time: less than 10 sec.
MOUNTING
When mounting the CE073 series isolator with a component
placement machine, a non-magnetic tool should be used since
there is some magnetic leakage from the isolator.
