Repair and Modification of PCBA’s

Repair and Modification of Assembled Printed Circuit Boards


This program is designed to teach a series of basic repair techniques for damaged electronic assemblies.
The decision whether or not to repair damaged printed circuit board assemblies usually comes down to economic considerations. The cost of repairing a board is weighed against the cost of the board; the cost of components already in place at the time damage was sustained; the cost of labor up to the time of damage; cost of overhead; and so forth.
For the purposes of this program, we will assume that a determination has been made to make a repair. To get the most from this program, you should have a working knowledge of the electronic assembly process; workplace safety; proper use and handling of chemicals, cleaners and solvents; clothing requirements; ESD protective procedures; and soldering basics, including the use of flux and flux cleaners.

Let’s begin by understanding that all repairs have three sections:

  1. Analysis — where the extent of damage and a course of action is determined;
  2. The actual work of the repair process you have decided to use;
  3. Three is evaluation and testing of the repair once you have finished.

Each of these three sections have a number of individual process steps that we will explain in detail during the training cours.

Duration
