PCBWay other Services

Advanced PCB - When you order advanced PCBs from PCBWay, you are buying quality that pays for itself over time. In the comparison chart below you can see where the advanced PCB is unique or goes beyond the IPC standard.

Assembly Service - PCBWay offers turn-key PCB assembly services in prototype quantities or low-volume to mid-volume production runs. They handle the whole process including: ordering all the components, PCB manufacturing, PCB assembly, testing and final shipment.

How to make PCB by ironing method ᐅ

For make PCB you need PCB layout. download the PCB layout and print it by laser printer on photo paper. Then cut the PCB layout. Then press the PCB layout by iron on copper clad board. Press the iron 10-15 minutes. Then leave the PCB for cool down 10 minutes. When the PCB will cool, put the PCB in water and move the PCB layout to copper clad board. Then put the PCB in ferric chloride [FeCl3+H2O] for etching 10-15 minutes. when etching was end, clean the PCB by water. Then make hole on PCB. And then press the upper side print of PCB. Now your PCB is ready, mount components by instruction.

How to test this Crossover

After complete this board don't forget to series light test. Check this board without OP-AMP.

If series light not glow, then put the OP-AMP to IC socket.

But before place OP-AMP, check per IC socket 4 no pin and 8 no pin (+ and - both). You get here 30V

For OP-AMP you can use - 4558D/ TL072/ TL082/ NE5532.

After place the OP-AMP, check three output and one input voltages. Here you get no voltages = 0.00V

If you get same voltages, then connect this crossover to amplifier.
