SOLDERING & HANDLING CONDITIONS
I. Soldering Conditions
1. Preheat from room temperature to 150°C within
120 seconds (see item
Fig. 1).
2. Soldering: 3 & 4mm resonators can be soldered
between 210 to 250°C (see Fig. 2).
6mm resonators can be soldered between 210
to 230°C (see Fig. 3).
The resonator must be kept at a temperature
greater than (Peak –30°C) for more than
30 seconds (see
Fig. 1).
3. Cooling: Gradual cool down suggested
(see
Fig. 1).
4. Suggested Solder: Eutectic cream containing
RMA flux.
5. Land Pattern: It is suggested to use the full width
and 3/4 the length of the resonator for grounding
(see Fig. 4).
II. Handling & Storage
1. Avoid contact with hands as body oils promote
oxidation.
2. Store at < 50°C and < 80% relative humidity.
3. Avoid excessive force on the resonator terminal.
