9. CONNECTING LCDs
- Fixed pins have a typical pitch of 2,54mm. (Pls refer to mechanical specification).
- LCD for elastomeric connectors (zebras) may have thighter pitches. Please regard tolerances and pitch
of elastomer connector.
10. SOLDER CONDITIONS FOR LCD WITH FIXED PINS
min. typ. max.
Solder temperature t.b.d. ~ 235°C 260°C
Solder duration t.b.d. 2 seconds 5 seconds
Distance to glass substrate 4mm 6mm t.b.d.
t.b.d. – to be discussed !
11. CLEANING OF LCDs
- LCDs have a protective foil on top of the front glass. This foil should be removed at the latest possible
stage.
- If there is a need of cleaning, you may use freon or alcohol with a soft fabric, as front polarizers are
sensitive to physical damage.
- Pls also note this protective foil on the rear side, in case you use transflective model-types.
- Do not use ultrasonic for cleaning of PCB once LCD is soldered.
12. HANDLING PRECAUTIONS
- As polarizers of LCD (front and rear-side) are sensitive, they must be handled with care.
- DC Voltage or drive voltage higher than specified voltage will decrease the lifetime of the liquid crystal
display panel.
- If any fluid leaks out of a damaged glass cell, wash off any human part that comes into contact with soap
and water. Never swallow the fluid. The toxicity is low, but caution should exercised at all times.
- LCD is made up of glass, organic sealant, organic fluid and polymer based polarizers. The following
precautions should be taken when handling:
Keep the temperature within range for use and storage. Excessive temperature and humidity could
cause polarization degredation, polarizer peel-off or bubble generation. When storage for a long period
over 40°C is required, the relative humidity should be kept below 60%.
