Production and testing

+ +This document gives a high-level description of the production test process +for atben and atusb boards, plus - in the case of atusb +the production steps required between the boards leaving the SMT line and the +actual testing. +

+The testing serves two purposes: +

    +
  1. Ascertain the correctness of the preceding production steps, and +
  2. identify suffering from random production flaws and either discard + them or prepare them for repair. +
+The results of testing and fault analysis also provide feedback for the +SMT process and steps preceding it. +

+The following diagram illustrates the workflow: +

+ +

+Only atusb boards contain firmware and need flashing (which is +a two-step process, see below). The functional tests and further fault +analysis are largely the same for atben and atusb. +

+Devices accepted for further use can then be packaged for shipping. +Defective devices can be discarded or retained for a deeper analysis. + + +

Terminology

+ +
+
Ben
+
a device capable of hosting the atben and atusb-pgm + boards. In the production process, a Ben can perform three different + roles: +
    +
  1. Host an atben board acting as DUT +
  2. Host an atben board acting as reference +
  3. Host an atusb-pgm used for flashing the boot loader +
+ In this document, we assume that a single Ben is used in all + three roles, with the board in its 8:10 card slot changed as + the role requires. +
PC
+
a device capable of connecting to a Ben via USB, and of hosting an + atusb board. In the production process, a PC can perform three + different roles: +
    +
  1. Host an atusb board acting as DUT +
  2. Host an atusb board acting as reference +
  3. Control a Ben via USB (for convenience) +
+ In this document, we assume that a single PC is used in all + three roles, with one USB host port permanently connecting to the + Ben, and a second USB host port populated with atusb boards + as needed. +
DUT
+
Device Under Test. An atben or atusb board that + has left SMT, and is being prepared for testing or in the process + of being tested. +
Reference
+
An atben or atusb device that is known to work and + and that acts as a peer for RF communication with the DUT. +
SMT
+
In this context, the actual process of soldering components to + the unpopulated PCB, and all related tasks providing an input to + this process. Such related tasks include the configuration of the + SMT line, and testing and conditioning of the components to solder. +
