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 […]

Spring 2016 3D SMD: Geared Stepper Motor Trade-Off Study

By Bao Loc Doan (Project Manager) Requirement L2 – 3: Makeblock XY Plotter motors shall be modified to 0.05 mm error tolerance. Table of Contents Introduction The Makeblock XY Plotter came with two (2) Makeblock 42BYG stepper motors. The stepper motors control our x-axis and y-axis movements. Geared stepper motors were given as a suggestion […]

Spring 2016 3D SMD: Z-Axis Rapid Prototype

  By Henry Nguyen (Electronics and Control) Table of Contents Introduction For our Z-Axis, we purchased a Thread Drive Pack from Makeblock which is able to move our thread drive beam up and down with great precision. This kit came with a DC Motor; however, for our uses, we found that using a stepper motor […]
