Spring 2016 3D SMD: Z-Axis Beam
By Henry Nguyen (Electronics and Control) Table of Contents Introduction When running our accuracy tests, I found that the current beam on our Z-Axis would wobble. After carefully observing the wobbling, I found that this will be a major problem when we needed to assemble a PCB with surface mount components. The wobbling will cause […]
Spring 2016 3D SMD: Critical Design Review Debrief
By Bao Loc Doan (Project Manager) Table of Contents Introduction The Critical Design Review presentation was supposed to be a time where the 3D SMD group could show the customer and the review board how far along we’ve gotten since the PDR. It was expected that we should have the core design aspects of the […]
Spring 2016 3D SMD: X-Axis, Y-Axis, Z-Axis, A-Axis, and Origin Brackets
By Henry Nguyen (Electronics and Control) Table of Contents Introduction For our 3D SMD pick and place machine, we were able to get most of our software for controlling our stepper motors done. The only thing left to do is to design and manufacture proper brackets for each of our stepper motors since we […]
Spring 2016 3D SMD: Software
By Christine Vu (Missions, Systems, and Tests) and Henry Nguyen (Electronics and Control) Table of Contents Purpose This is a summary of all Arduino code modifications for the pick and place machine to work with our needs. Modifications for Java can be found here. Our files can be found here: https://github.com/cvuchristine/MakeblockPlotter.git Required Arduino Code modifications Pinout […]
Spring 2016 3D SMD: Verification Test – Vacuum Head Design
By: Christine Vu (Missions, Systems, and Test) Table of Contents Vacuum Head Test To verify the size of the vacuum nozzle design, a test will be conducted to determine that the size of the vacuum provides sufficient pressure to pick up a SMT component. Requirements Section 5 Vacuum Head Design I SMT component size 0402 […]
Spring 2016 3D SMD: Origins and Scaling
By Henry Nguyen (Electronics and Control) and Christine Vu (Missions, Systems, and Tests) Table of Contents Introduction In order for us to accurately pick and place components on our pick and place machine, we must be able to identify our origins. Once finding our origins, we will be able have proper Gcode location coordinates […]
Spring 2016 3D SMD: Verification Test Plan
By: Christine Vu (Missions, Systems, and Test) Table of Contents Purpose Verification Tests will be conducted to verify the requirements based on the Verification Matrix. Requirements for Verification Tests Section 1 EE400D Assembly The SMD pick and place machine shall pick up and place down all SMT components provided by any EE400D PCB up until […]
Spring 2016 3D SMD: Vacuum Pump Trade-off Study V2
By Henry Nguyen ( Electronics and Control) Table of Contents Introduction In order to find a vacuum pump that best suits our pick and place SMD machine, we needed to compare several different options. Considering pressure and cost will be crucial for this trade off study. Our goal is to find a vacuum pump that […]
Spring 2016 3D SMD: Me Uno Shield and Software
By Henry Nguyen (Electronics and Control) Table of Contents Introduction Originally when purchasing our X-Y plotter from MakeBlock, we were given a Me Orion microcontroller. This microcontroller was enough to power two stepper motors for our X and Y movement; however, because we are modifying our X-Y plotter to become a 3D SMD pick and […]
Spring 2016 3D SMD: Aluminum Surface Table
By Henry Nguyen (Electronics and Control) Table of Contents Introduction For our 3D SMD pick and place machine, it is extremely vital that we have an aluminum surface table in order to put our PCB, reel feeders, and IC tray. This surface table is to be the exact size of our makeblock X-Y plotter with […]
