5 Things You Need To Know About Rework and Repair

The IPC-7711/7721 course deals with the topics & procedures of rework and repair.  Within manufacturing, errors in production arise, and rework operators are needed to repair and troubleshoot any defects.  In this blog we will discuss the five things you need to know about rework and repair.

The Meaning of Rework, Modification, and Repair

The term rework is described as to make changes to an original version.  When a rework operator performs any type of rework, they must be within full compliance to drawings and or specifications.  Modifications made to the product are considered revisions to satisfy a new criteria or design.  Repair is the act of fixing or mending a product that has been damaged or is no longer functioning.

Types of Equipment Used

In an IPC-7711/7721 class, we use similar rework stations operators would utilize in the workplace.  Some equipment we use in our classroom are the Hakko 3-port Rework Station, Hakko SMD Hot Air Rework System, and desoldering hand tools.

Skills You Will Learn

Within an IPC-7711/7721 class, students will only learn how to use various tools, but how to apply learned skills to various processes.  Removal and repair of surface mount and through-hole components, cleaning, and conformal coating are a few processes covered.  Students will be able to improve on their skill level based on what they have learned.

The Effects of Rework and Repair in Manufacturing

In the industry, the amount of time and money it takes to rework and repair products can be costly.  At times a part can be reworked or repaired numerous times until the product no longer functions, and the company ends up wasting money on wasted parts.  On the other hand, there are cases where rework can salvage the product to avoid a total loss.  Improving employee training and emphasis on pre-production processes are some ways in implementing a strategy to minimize rework and excessive scrap.

Becoming A Certified Rework Technician

IPC offers the CIS (Certified IPC Specialist) and CIT (Certified IPC Trainer) levels for the IPC-7711/7721 course.  To obtain your certification you will need to register with an authorized IPC Training Center that offers the course.  For a listing, please visit https://www.ipc.org/certification-centers.
