7、使用說明Instructions：

⑴   LED儲存：

　　建議存儲溫度10攝氏度-55攝氏度，濕度：30%-65%，包裝袋密封保存。為了保證產品質量，外包裝袋打開前，出廠后一年內使用，外包裝袋打開后，建議28天內使用。

      LED storage：

suggest to sealed stock in under the temperature of 10℃-55℃，humidity of 30%-65%.In order to keep a good quality, pls use it within 1 year after the prodcution date; and use it out within 28days after open the package.

⑵   拿取方法：

　　接觸LED檢查時需戴手套或者手指套，工作臺面也要接地，包裝袋開口后要及時封口，防止引腳氧化。打開包裝后，操作人員應該使用鑷子夾持LED兩側，避免手接觸LED正面。

When taking or touch the LED, pls make sure to wear the gloves. Seal the package in time in orde to avoid the pin oxidation. When openning the package, need to use the weezers clamped on both sides of LED in order not to touch the face of the LED.

⑶   安裝Installation：這一過程主要是靜電的防護     　　　This process is mainly to protect the static electricity：

    ①   生產前檢查機臺設備接地線是否正常；

    Check if the grounding wire of the machine equipment is normal before production;

    ②   檢查人員靜電環是否正常，檢查靜電的金屬與人的皮膚接觸緊密；

    Check if the static ring is normal, check static metal and human skin contact closely;

    ③   在安裝時**要求作業人員戴好防靜電手套或者防靜電手指套；

    Check if the workerswear anti-static gloves;

   ④   作業臺面鋪好靜電膠布，膠布之間應相互連接接地；

    Check if the working table is paved with electrostatic rubber cloth, and the rubber cloth is connected to each other.

⑤   開封后**在二十四小時內用完，否則可能會引起燈腳氧化生繡。

   After opening the seal, it is better to use it   out in 24hors, otherwise it may cause the oxidation of the foot.

⑷   建議使用低溫錫膏進行迴流焊，溫度曲線如下圖所示：

It is recommended to use low temperature solder paste for reflow, and the temperature curve is shown in the following diagram.

①   預熱區

　　升溫速率為1.0-3.0攝氏度/秒，在預熱區的升溫速度過快，容易是錫膏的流移性及成分惡化，易產生爆錫和錫珠現象。

       Preheating area

The temperature speed is 1.0~3.0℃/S. If the temperature rises too fast, it is easy to cause paste mobility and component deterioration, then cause the tin explosive and phenomenon.

②   浸潤區

　　溫度110-130攝氏度，時間90-100秒適宜，如果溫度過低，則在回焊后會有焊錫未熔的情況發生（建議溫升速度<2攝氏度/秒）。

    Infiltrating area

The temperature is 110~130℃, 90~100s is the most suitable. If the temperature is too low, then the solder will not melt if it is rewelded. It is recommended that the temperature rise speed is <2℃/ s.

③   回焊區

　 尖峰溫度應設在170-180攝氏度。熔融時間建議把138攝氏度以上時間調整為50-80秒。

    Reflow Area

The peak temperature should be set at 170~180℃. The melting time suggests to adjust to 50-80 seconds when   above 138℃

④   冷卻區

　   冷卻速率<4攝氏度/秒

      Cooling   Area

Temperature cooling spead is better <4℃/ s.

⑸   LED隨著電流的增加和溫度的升高，他的使用壽命會呈某種曲線下降，導致LED衰減加快。

With the increase of current and temperature, the life of LED will decrease, which leads to the acceleration of the attenuation of LED.

⑹   建議在設計PCB時要有接地電路。特別注意LED的使用環境：溫度在零下30攝氏度-55攝氏度之間，濕度在65%之間，否則將會有靜電擊穿和大電流擊穿導致死燈。

It is suggested that a grounding circuit should be used in the design of PCB. Pay special attention to the usage environment of LED: the temperature is between -30℃ to 55℃, and the humidity is between 65%. Otherwise, the LED will be broken by electrostatic and high current breakdown.

⑺   產品光電性能級別由Hea-Keys™公司自行決定，各不同級別的產品光電性能有所差異，請客戶根據自己使用條件自行決定使用方法。

The photoelectric properties levels are decided   by Hea-Keys™. There are differences between the different levels of products, please use it in a stuitable way according to the using conditions of the clients.
