Soldering and Desoldering Tips and Tricks

Video Walkthrough

How do I turn on the soldering irons in PRLTA 103?

How do I solder through-hole components by hand?

How do I solder surface mount components by hand?

Capacitors, diodes, inductors, resistors

DPAK-style components (MOSFETs, voltage regulators)

Integrated circuits (ICs)

How do I solder surface mount components using a reflow oven?

This method involves applying solder paste to the pads on the PCB, manually placing your surface mount components into the solder paste, and baking the board in a special oven to solder the entire PCB at once. This method is not really easier than hand soldering for one-off PCBs; you are trading one set of challenges for a different set. If you are interested in using solder paste and the reflow oven to solder your components, please contact Osama Jameel in PRLTA 109.

SPI & Shift Register Tutorial

Serial Communication - SPI & Shift Register Tutorial

Objectives

Getting familiar with the SPI serial communication protocol using MCC under the MPLAB X programming environment to program the PIC16F18446 Curiosity Nano development board and control a shift register to drive 8 LEDs on and off. In this tutorial, you will learn to set up the Serial Peripheral Interface (SPI), Shift Registers, and 3 of the major numeral system (decimal, binary, and hexadecimal).

SPI Communication with the SN74HC595 Shift Register using Timers

Objectives

To develop and demonstrate individual proficiency in:

  1. Using SPI communication to control LEDs connected to a shift register

SPI Communication with the SN74HC595 Shift Register using Timers (Part 2)

Introduction

This tutorial builds off of Part 1. Go Back and start there if you haven’t yet completed it.

SPI Motor Controller (PIC)

Introduction

This is a basic tutorial for the steps required to get SPI working on the PIC18F47Q10 Curiosity Nano

Stepper Motor Selection and Control

Stepper Motor Selection

There are four variables to consider when selecting a stepper motor

Steps and additional notes for Board Layout

In the hopes that it will help anyone that is still working on the PCB, here is a list of the steps needed for this homework assignment with the corresponding blog posts and some of my comments. I also added some links at the bottom for specific errors I have seen mentioned so far. Please comment if there are any parts of the process that you would like more details on and I will try to add to this post.
