(this does not apply in the case of a non-halogen type of flux.) it is recommended that you protect the lcd surface with a cover during soldering to pr event any damage due to flux spatters. when soldering the el ectrolumine scent panel and pc board, the panel and board should not be detached more than three times. this maximum number is de termined by the temperature and time conditions mentioned above, though there may be some variance depending on the temperature of the soldering iron. when remove the electroluminescent panel from the pc board, be sure the solder has completely melted, the soldered pad on the pc board could be damaged.
