Because this matter is too difficult to operate, the control of every detail from the whole to the zero is too high, so it is easy to find that it is not connected as you do it.

After brushing, Shen Chong first drew out the overall shape of the back panel patch, which was the size and thickness of the bank card were exactly the same as the bank card.

He also indicated the material of the back panel, a special metal that was just launched, has a high cost, but can produce strong hardness when it is very thin.

This material selection just meets the material requirements for verifying the back plate. As for the cost, sorry, that is not something you need to consider.

Then Shen Chong continued to do the dots on the back plate, ensuring at least one support column per square centimeter on average to prevent the back plate from deforming and crushing the components inside.

Some of the technicians from the Science and Information Department immediately raised objections.

"When Mr. Chen did this, the design of the PCB circuit board is extremely difficult to improve! The PCB board must avoid these support columns! Why doesn't he use a keel to support it?"

Mr. Mouse angrily scolded, "Shut up! Watch the big guy show his operations!"

Two hours later, watching the projector pulling and extending lines like ants climbing trees, the people in the Science and Technology Information Office could no longer speak, and only the big words flying from the sky remained in their hearts.

Damn it!

The dense PCB printing lines are vividly displayed on the paper, with beautiful and neat lines and do not meet each other.

What's even more terrifying is that Shen Chong did this so quickly that it was outrageous, as if he had thought about everything when he started.

But everyone is still a little unaware of it.

The technicians who are dedicated to designing PCB circuits are all confused.

"This is unreasonable. If you can't connect all spare parts in this way, right?"

Click click!

Suddenly, Shen Chong started to start a starting point on the newly drawn PCB circuit board again.

The technician suddenly realized, "Damn it, it turns out that it is a double PCB cable, no wonder."

Two more hours passed and he started to complain again.

"This is not enough, right? Damn, Mr. Chen started to punch holes again! I was so proud, why did he think of it? The newly punched holes and the holes on the first layer were completely avoided, and the wiring positions of the printed circuit were also completely avoided!"

There were some people who couldn't hold on during the intermittent period. Everyone should have gone to bed, but no one was willing to leave.

Finally, another three hours passed, and Shen Chong finally finished drawing the PCB circuit board design.

The technicians just want to offer their knees.

Chen spent less than ten hours to complete the three-layer sterling silver printed circuit design that does not interfere with the ultra-thin PCB boards.

The thickness of the entire PCB board is less than 0.1 mm, three layers!

He also considered the material of the circuit board and the insulating painted material clearly. Some circuits with strong voltages were perfectly staggered, and there was no possibility of voltage breakdown and short circuit.

Damn he also reserved the dozens of holes he had previously knocked down!

One-time molding!

No rework!

There is only one explanation for him to do this.

Before he started work, he had indeed finished drawing in his mind.
Chapter completed!
