Executive Summary By Bao Loc Doan (Project Manager) Program Objective When humans manually pick up and place down surface mount components onto a printed circuit board (PCB), there are normally problems with efficiency. A surface mount component may be placed at the wrong spot or dropped. These mistakes cost the user money as well as […]
By Christine Vu (Missions, Systems, and Test) and Henry Nguyen (Electronics and Control) Working Area Test Working area is defined by the area that includes PCB to assemble, reel feeders, and IC tray. To verify that our design meets the size criteria for working area, a test will be conducted to calculate its parameters. Requirements […]
By Christine Vu (Missions, Systems, and Test) and Henry Nguyen (Electronics and Control) Reel Feeder Design To verify the reel feeder design has the correct function, a test will be conducted to determine its parameters and design. Requirements Section 4 The SMD pick and place machine shall have four 8mm reel feeders and one IC […]
By Nasser Alsharafi (Manufacturing) The Custom 3D Printed IC Tray The custom 3D printed IC tray is designed to house 21 evenly spaced different sized common IC components. One of the largest and most desired ICs we will be using is the ATMega32U4 IC. This IC is the standard for which we will calculate our […]
By Nasser Alsharafi (Manufacturing) The Reel Feeder The Reel Feeder shown above is a major component of the pick and place machine. This component is fully automated, and has custom fabricated aluminum parts. It is made up an aluminum base, four SMD part reels, four servos, four legs, and one axle, 4 spacer drums. The […]
By Henry Nguyen (Electronics and Control) Introduction For our Z-Axis actuator, we found that our thread drive will constantly cause our nozzle to shift towards the left when going down and towards the right when going up. This was caused by the two 4mm rods and the thread screw we were using. A slight solution […]
By: Christine Vu (Missions, Systems, and Test) Cable Test A test will be conducted to determine that the bending radius will have a minimum bend radius of 10x its cable diameter. Requirements Section 1 EE400D Assembly The SMD pick and place machine shall pick up and place down all SMT components provided by any EE400D […]
By Henry Nguyen (Electronics and Control) 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 our machine to […]
By Bao Loc Doan (Project Manager) 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 project, in manufacturing, […]
By Henry Nguyen (Electronics and Control) 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 purchased 2 new […]
