Electronics Production

It is time to manufacture a PBC, this week we will manufacture the PBC Quentorres and we will live the experience of the process.

the assignment was:

group assignment: characterize the design rules for your in-house PCB production process

individual assignment: make and test a microcontroller development board

extra credit: personalize the board, extra credit: make it with another process

Group assignment

the group assignment was carried out at the facilities of the "Universidad cientifica del sur" in the fab lab.

For the group task we planned how we would perform a milling test from an image in .PNG format that we downloaded from the academy work files.

You can see the complete documentation on the group's web page

what did i learn in the group assignment?

The importance of having PNG files correctly plotted

The ease with which the Mods platform allows us to make the traces.

The CNC is easy to operate, just be careful when interchanging the milling tools.

We must be careful when calibrating the "Monofab" CNC Router.

Choose the right milling tools for each process to be carried out.

Individual assignment

This time I will build option 2 where the XIAO RP2040 can be removed using the following connectors.

This is the list of all the components required to build the Quentorres pcb.

Item	Components	Amount
1	SEEED STUDIO XIAO RP2040	01
2	CONN HEADER SMD 10POS 1.27MM	01
3	CONN HEADER SMD R/A 6POS 2.54MM	01
4	Tactile Switch SPST-NO Top Actuated Surface Mount	01
5	LED BLUE CLEAR 1206 SMD	03
6	RES 1K OHM 1% 1/4W 1206	04
7	RES 499 OHM 1% 1/4W 1206	01
8	CONN HDR 7POS 0.1 TIN SMD	02

All these components are located in Jr. Paruro in downtown Lima, Peru.

to locate us, we use google maps. click to see the google map with the coordinates.

The first step is to fabricate the Quentorres PCB, for this process we will use the Mono Fab SRM-20 Milling Machine.

After configuring the file using mods, we proceed to send it to cutting.

Accessories: mills 1/64 mill used for milling and 1/32 mill used for cutting

PCB setup process for cutting.

first test was unsuccessful, we configured once again...

final result of the PBC Quetorres, this personalized with my name, I love it!!!!

once the QUENTORRES is manufactured we proceed to solder the components, it is a job of great precision since I have no experience in this process.

It took me many hours to solder some of the components, I did not finish, but I will continue working on this process until the QUENTORRES is working.
