To get rid of bad PCB, you can have 5 tips to help you to solve this problem:

Firstly, You have to first of all research and select suppliers earlier in the design circle. Talk with suppliers' customer service technical teams or sales teams, and determine just how well they can respond with quality across the whole range of your anticipated project style.

Secondly, you should optimize for cost and performance before layout. In a general sense, the fewer components that are needed to implement your circuit, the more reliable your end product.

Thirdly, develop your layout to the fabricator's sweet spot.?Regardless of whom you choose, your fabricator has a sweet spot-that place where designs are well inside the middle of the manufacturing process window.

Fourthly, verify your layout's manufacture ability with a supplier DFM tool.

Fifthly, manage prototyping costs and hidden costs,you can choose Elecrow pab service as your partner as it can offer you good service due to your need and lower cost.

E90 IS THE ERROR CODE IT IS SHOWING


E90 is a communication error between the main pcb and the display pcb.Check the blue wiring loom that goes from the main pcb to the display pcb.normally it is a bad/loose connection on the display pcb end.clean pcb tracks and tighten the blue connector loom pins up and hopefully it will work.if it doesn't solve the problem then you could have a faulty display pcb or main pcb.

Getting lines across the monitor screen


It may have one of reasons:
1. "Dirty" supplying voltage in the monitor - check all electrolytic capacitor.
2. Bad controller chip - check if it gets extremely hot when working, also you may see darkened area on other side of the PCB where that chip is located.
3. Loosed connection between controller PCB and the display itself - disconnect the cable and clean contacts, especially of blade connector on display side, check if there are some overpressed contacts.
