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 PCBWay 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 must upload the Gerber File and select the quantity, color, silkscreen, thickness, etc. Then choose your country, and shipping method, and then Pay. PCBWay 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 ordered White PCB. But you can choose your PCB color. PCBWay provides 9 color solder masks - 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. The maximum Layer is up to 14 Layers. If you order PCB for the first time at PCBWay, you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.
