2、ldering iron and its tin very well.Use the wire brush but not spray cleaners such as Freon to clean the soldering surface.Adopt the melting ways:a) The temperature of soldering horn range from 350 to 390.b) Heat up the parts pin, until soldering tin is molten.c) Use the desoldering pump to suck out

3、the molten soldering tinquickly.Note: Quickly operating can prevent superheating the electronic-plating copper.Adopt the following soldering ways.a) The temperature of soldering horn range from 350 to 390. b) Hold the soldering iron and welding rod pointed to the parts pin,until soldering tin is mol

4、ten. Then move the soldering horn quickly to the location that you want to solder. Note: Quickly operating can prevent superheating electronic-plating copper of printed circuit board.c) Check the welting zone carefully, then brush the unwanted soldering tin away with a wire brush.Unsolder/Replace IC

5、Notes:Do not touch the IC body directly with soldering iron. Pre-heating soldering iron at about 130 for some seconds avoid the damages caused by IC heated suddenly. For normal IC, the temperature of the solder horn is about 350, and can increase to 390 for some bigger IC.Use the filamentous welding

6、 rod and solder which thickness is about 0.3mm to solder thin IC and add the solder as needed.Replace the IC carefully and solder it quickly.After unsoldering the IC, clean the basic board carefully to ensure the board is usable.Prevent the molten soldering tin dripping on the board which will engen

7、der a short circuit.Aim at the first terminal and fix it, then aim at other terminals for correctly inserting IC. You can solder quickly just like this.Before operating, please make sure the IC is unusable. Do not unsolder repeatedly. During soldering especially soldering a thin IC with many pins, c

8、heck the weld carefully.After replacing, check that there is not soldering leak, rosin joint, short circuit and so on. Unsolder:Use the soldering iron to melt the soldering tin.Before unsoldering IC, suck out the molten solder tin.ReplaceMake sure all the IC pins are on their correct location, then

9、solder.Use a wire brush to clean the welting zone.Items of Safety Attention1-6U After unsoldering the unusable diode, nip its body and take it out.Bend the two pins and the diode is vertical to circuit board.Check the polarity of the diode, then place its pins to the correct location. Pin the joint

10、and solder it.Check the weld carefully. If the surface of the weld is not smooth, please solder it again.R - Repair the warpage copper as following: Use a sharp knife to scrape the unusable copper and the unwanted solder off.Make one side of the lead bent like a small “U”, then put the “U” to IC pin

11、s and solder. Another side of the lead is extended until overlap with the well copper then solder. Cut the unwand lead.T DD No sound or sound distorted when playing, please check the DVD part.N Before operating, read these notes as following to prevent the static charges damageing the laser head whe

12、n reading the laser led.Lay an electric rug on the working table and the replaced parts are packed in black package.The electric rug is grounding by put on the electric base.Then put your hand on the electric rug and connect the static handle with the electric rug. Make sure the electric rug and the

13、 working table are grounding. During the operating, do something such as operating on the electric rug to avoid the static charges touching the laser parts.After that, you can begin to take the laser parts down. When replace the laser parts, please do something to make a short circuit and remenber t
