Application of common sense and performance testing are as follows:
(1) soldering iron: The soldering iron (up to 30W) temperature does not exceed 300 ℃; welding time is not more than 3 seconds; welding position The at The 2 mm from the gel.
(2) The dip soldering: The dip soldering maximum temperature of 260 °; The dip soldering time is not more than 5 seconds; dip soldering position The at The 2 mm from the gel.
Pin forming method:
(1) must The 2 mm from gel to bend bracket.
(2) The stent fixture or done by professionals.
(3) The stent must The completed before welding.
(4) stent  need to ensure The pin and spacing consistent with  circuit board.
LED installation method
(1) Note that  perimeter of  arrangement  various types of devices to prevent wrong polarity. Devices not  get too close The The heating element, The working conditions do  exceed  limits of its provisions.
(2) Be sure not to install pin deformation LED.
(3) When decided  calculate good face and circuit board Pitch dimensions and tolerances in order to avoid  bracket by excessive pressure in hole installed.
(4) when installing LED intended to build  positioning guide sleeve.
(5) before return to  normal soldering temperature must be avoided make  LED be any vibration or external .
Wash
When chemical cleaning colloidal must  especially careful, because some chemicals on  colloid surface damage and cause discoloration such as trichlorethylene, acetone. Available ethanol wipe, dipping time  not more than three minutes at room temperature.
Operating and storage temperature:
(1) LED light-emitting diode Topr-25 ℃ to 85 ℃ Tstg - 40 ° C to 100 °

(2) LED display Topr at 20 ° C to 70 ° , Tstg-20 ° The to 85 ° C
(3) OUT-DOOR LED pixel pipe Topr-20 ℃ ~ 60 ℃, Tstg-20 ℃ ~ 70 ℃
