Display Soldering Conditions
A-5461BS
The recommended conditions for soldering are as follows. Because the component is made with epoxy resin, the
units are susceptible to heat. Therefore, the preheating and soldering temperatures should be kept as low as possible to
avoid damage.
1 . Manual Soldering Conditions(with 1.5mm Iron tip )
Iron Tip Temperature: 350°C Max, Time: 3s Max
Position: The iron should be situated at least 2mm away from the root of the leads.
2 . Through the Wave Soldering Conditions
Wave Soldering Profile For Lead-free Through-hole LED
3 . Soldering General Notes:
a. Toplight recommend manual soldering to be used only for repair and rework purposes. The soldering iron should
not exceed 30W in power. The tip of the soldering iron should not touch the reflector case to avoid heat-damage.
b. Maintain the pre-heat and peak temperatures with dip units as low as possible and the times as short as is feasible,
since the products are susceptible to heat during flow soldering.
c. After soldering, allow at least three minutes for the component to cool to room temperature before further
operations.
d. If components will undergo multiple soldering processes, or other processes where the components may be
subjected to intense heat, please check with Toplight for compatibility.
