Is it possible to replace an automotive wiring harness with PCB?

Is it possible to replace an automotive wiring harness with PCB? For example, just have the cables attached on either end of the circuit to eliminate a bunch of messy cableage in between.

That can be realized with the help of micro-controllers, but you have to use high clock rate MCUes with this.
Divide sections into 3 parts. Central, Front and rear.

Take all the inputs such as light switches, brake paddle switches, etc to Central MCU. Remember switches with interrupt handling.
·Serialise the data with I2C or CAN or USART or any sort of serial communication.
Make rear and front receiver parts with used serial methods.
and you are done.

Pros

Cons

Less wiring

Less loss of voltage

Digital

Flexible

Can add more features

Lots of programming

Spike’s from the spark plug does harm your serialised signals.

MUC is low voltage device

Motorbike is Hot and high voltage.

More Isolations and more circuit complexity.

(Remark: According to our experience, more attention should be attached on voltages and external noise.)

I forgot a resistor on my PCB prototype – how do I add one in?

I need to add a resistor into a data line on my project. The data line is a trace and carries low speed data. A through-hole resistor will be fine. The pins for both ends of the trace are exposed, but how do I add the resistor and remove the trace?

Can leaded BGA chips be reflow soldered with lead-free process?

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable. But now BGA chip is only available in lead-free balls. is it ok to solder leaded BGA chips with a lead-free (thus, higher temperature) process?

How do components not get knocked off or fall off during reflow?

Last week we visited a PCBA factory. We were looking at reflow ovens. A lot of them have a metal conveyor belt the boards sit on. On a double sided board, when you put the board on the metal belt, won’t the metal belt knock components off as they are only held on by paste?
