Operation Tips
1. Please do not press emitting surface;
2. Please do not pour out products from trays or overlay them;
3. Keep the power supply lines 2-3mm striped and tin immersed;
4. Do not touch the emitting surface or the white dam by the soldering iron during soldering process;
5. Soldering time should be less than 5 seconds.;
6. Keep the soldering point clean and neat with no bulge, bend or cold-joint.
7.Instant test time less than 3 seconds.
8.Recommend to use thermal grease with conductivity >2.5.
9.Please keep the thermal grease inclusion-free;
10.Thermal grease spreading area should be a bit larger than the led substrate;
11.Thermal grease evenly spread with thickness about 0.1mm;
12. Place led flatly and do no push from side in case grease scraped;
13. Lens cover should be 0.2mm diameter larger than the COB emitting surface.
Service Conditions
