Led Circuit Board Is A Printed Circuit Board

Shenzhen Inno Circuit Co.,Ltd | Updated: Jul 04, 2017


LED circuit board, is a printed circuit board, is better in the thermal conductivity of the aluminum plane printed on the plane, and then welded to the top of the electronic components.

There are led circuit board reflow must be set to reflow the temperature of the reflow, or it is likely to cause the loss of bulb lamp beads caused irreparable damage caused by the phenomenon. LED PCB Then there are led circuit board reflow how to work hard to do such an unnecessary loss of it.

First, there are led circuit board after the reflow soldering temperature curve must be adjusted after the first board to do a variety of quality confirmation OK after the batch to the production, LED PCB which is the factory quality management in the first confirmation of the work.

Second, there are led circuit board reflow soldering before doing welding work must look at the LED lamp beads factory specifications, see it all kinds of technical parameters

1, depends on LED lamp beads packaging material temperature;

2, depends on what LED welding substrate material, such as the general PCB (fiber board, etc.), aluminum plate, ceramic plate;

3, depends on the welding agent, is high temperature or low temperature solder paste, or resin;

4, according to the actual quality of LED reflow equipment to set, LED PCB see the LED reflow temperature range, very flow rate, fan, the district temperature settings and other parameters of control.

Third, there are led circuit board over reflow through the LED lamp beads of the general adjustment parameters of reference

The minimum temperature of 150-170 degrees can be, the maximum temperature is best 240-245 degrees (the maximum adjustable to 260, if 245 degrees can be dissolved, then do not tune to 260), 220 degrees above the time can not exceed 60 seconds, If the temperature increase, then 260 degrees of time can not exceed 10 seconds. LED PCB If it is 7 temperature zone, you can refer to the following settings: 160,170,175,180,190,210,245,220. If the LED lamp beads are silicone lens, you can use BI58SN42 solder paste, the maximum temperature of 225 degrees Celsius. If it is a PC lens, it is best not to use reflow soldering.
