Excess Current Protection Precautions For Using Of LCDs

 

 

Powertip Technology’s LCMs use CMOS LSI. Therefore, measures to protect static electricity have been taken through all the processes from manufacturing to shipping. When handling, take necessary care to prevent static electricity as you would any CMOS IC.

 

Do not take LCM from its anti-static bag until it is time to assemble:

LCMs are individually packaged in bags treated to resist static electricity. An LCM should not be removed from the bag until it is time to solder the terminals. When storing the LCMs keep them packaged in the anti-static bags, or a container that is resistant to static electricity, or in an electric conductive container.

 

Always use a body ground when handing an LCM:

Always apply grounding to your body while you are working with an LCM from the time it is taken out of the anti-static bag until it is assembled. When it is necessary to handle the LCM, once it is taken out of the bag, always place it in a electric conductive container. Avoid wearing clothes of chemical fiber. Cotton or conductive treated fiber clothes are recommended.

 

Use a no-leak soldering iron:

The soldering iron used for soldering the I/ O terminals of the LCM should be insulated at the iron tip or grounded on the iron tip.

 

An electrical apparatus is always required for assembly:

When the LCM is to be assembled with an electrical apparatus, this assembly should be grounded to avoid transmitting spike noise generated with the motor rotating.

 

Make the operation bench equal to the ground:

When the operation bench is grounded with an aluminum or steel plate, there is always the possibility of an electric shock being generated, when the impedance is too low. It is therefore recommended that an electric conductive (rubber) mat be used.

 

Peel off the LCM protective film slowly:

To the face of the LCM is a film to protect the display surface from contamination, flaw, adhesion of flux, etc. Peeling off this film too abruptly may cause static electricity to be generated. Thus peel off the tape slowly.

 

Attention should be paid to humidity:

50~60%RH is acceptable.
