Hello Friends, in this post I made a flat frequency Stereo amplifier, which can deliver up to 68W output per channel at 4Ω. For this amplifier, I use LM3886 IC. This IC is specially designed for active studio monitors, for its low noise distortion. And this IC is best for singers. This IC has in-built short circuit protection and over-voltage protection, So for this reason, this IC is more expensive than other IC. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to www.pcbway.com for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.
You just need to upload the Gerber File, and select the quantity, color, silkscreen, thickness etc. Then select your country, and shipping method and then Pay. www.pcbway.com will deliver your PCB within 7-10 days.
After one week I received my PCB. You can see the PCB quality, it's awesome. I have ordered Black PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder mask - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. And maximum Layer is up to 14 Layers. And If you order PCB the first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.
