Knowledge and performance testing product applications are as follows:

(1) soldering iron: iron (up to 30W) tip temperature does not exceed 300 ℃; welding time of less than 3 seconds; welding position at least 2 mm from the gel.

(2) Dip soldering: maximum temperature dip soldering 260 ℃; dip soldering time of less than 5 seconds; dip soldering position at least 2 mm from the gel.

Pin forming method:

(1) 2 mm from the gel necessary to bend bracket.

(2) Stent or fixture must be done by professionals.

(3) stent to be completed before the welding.

(4), stent placement and spacing of pins required to ensure consistency with the circuit board.

LED Installation

(1) Note that the arrangement of various types of external devices to prevent the polarity wrong. Not too close to the device and heating element, the working conditions should not exceed the prescribed limit.

(2) must not be the case of deformation in the pin installed LED.

(3) When the decision Kongzhong An installed, the calculation of good face and circuit board dimensions and tolerances so as not to pitch stand by excessive pressure.

(4) installation of LED, the construction of meaning with the guide sleeve position.

(5) in the welding temperature back to normal, it will have to avoid LED shock or by any external force.

Cleaning

When the chemicals must be particularly careful when cleaning gel, because some chemicals on the colloid surface damage and cause discoloration, such as TCE, acetone and so on. Available ethanol wipe, immersion time at room temperature does not exceed 3 minutes.

Working and storage temperature:

 LED LAMPS LED Topr-25 ℃ ~ 85 ℃, Tstg-40 ℃ ~ 100 ℃
