Q&A: How Many Iterations Do You Recommend for Scaling From a Prototype to Mass Production?

Here’s a question we answered in the Interrupt Slack channel after the From Concept to Launch: What It Takes to Build and Ship a New Device panel discussion. We’re sharing the answer on our blog to make it available to a wider audience. "" Quote  Starting from “I have a working MVP”, how many iterations …

Secondary Uses of Manufacturing Tests

31 May 2023 by Phillip JohnstonManufacturing tests and manufacturing firmware aren’t only useful on the production line. Your test stations, test scripts, and firmware can be leveraged to support additional activities without further burdening your software team. Here are additional uses to consider: Collecting Design Data Repair, RMA, and EFFA Processes Reliability Testing Certification Support Quality Assurance Collecting Design Data Your manufacturing tests are a prime data collection resource, and you should take advantage of that. You can get design data for every unit that you build. This allows you to look at performance/behavioral characteristics and distributions across your entire …

Basic Manufacturing Test Process

31 May 2023 by Phillip JohnstonManufacturing test flows are unique to every device, but there is a common, basic pattern that can be used as a foundation to build from. Basic Test Flow Testing is often broken into two distinct “sections” on the manufacturing line: Board-level testing (“SMT”) Assembled device (“FATP” for “Final Assembly, Test, and Packout”) SMT After SMA, PCBs are typically flashed with manufacturing firmware as a complete “panel” or as individual PCBs. At this time, basic information is provisioned, such as a PCB serial number. Following flashing, the PCBs will go through one or more test steps. …

Embedded Artistry’s Development Build Inventory Templates for SMA and FATP

If you are building an embedded hardware product, it is important that you keep careful track of parts and materials needed for your engineering development builds. This is essential even if you are already using a well-managed BOM. Development builds should be scheduled such that all materials are ready and QA’d to allow for the shortest, …

Additional Manufacturing Reporting Concepts

In the previous article I introduced some basic manufacturing reporting concepts. This article expands on the basics with additional reporting concepts you will come across while building embedded systems. Table of Contents: Throughput Yield Units-per-hour (UPH) Cycle Time Work in Progress (WIP) In Repair Test in Progress Fail on Line Loopers Further Reading Throughput Yield While overall yield …
