Surface Mount Devices (SMD) Reworking - three-day course

It is important that staff who are involved in rework of PCBs know how to replace surface mount components successfully – getting it right first time, every time; and this course provides students with the practical skills needed for the reworking of such surface-mounted devices.

Course overview

The course explores the use of a range of soldering processes including hot air, infra-red and solder paste and, when hand soldering, soldering iron use and using different gauges of solder wire, enabling staff to achieve the correct volume of solder for the type of connection.

Using a number of techniques, boards are prepared and soldered with lead-free solder and solder paste as well as leaded. A variety of solder compositions are used to ensure students have first-hand knowledge of the qualities and attributes of different solders.

The range of components used on this course is from 0402 chip components to SOTs, SOICs, MELFs and gull wing quad flat pack of up to 48 pins, including J-lead packages. We discuss and demonstrate techniques for the safe removal of failed components, board clean-up or preparation and then the onsertion of the new device. These techniques are also suitable for prototype circuit building.

Emphasis is placed on the diagnosis of faults that occur when reworking this range of components; these include dry joints, icicles, blow holes, insufficient as well asexcessive solder, de-wetting, non-wetting, hot tear, pad lift, tombstoning and misplacement. ESD implications are also discussed with respect to handling, storage and packaging.

Whilst visual inspection of a soldered joint is normally carried out between 4x and 10x magnification, some faults are examined at a greater magnification to enable to student to fully appreciate the issues involved in the defect. X-ray images are therefore also used to show how voiding can affect the quality of a connection.

Assessments at the end of the areas covered will result in an Electronics Yorkshire certificate being awarded to candidates who achieve the required standard. Within this programme students will also be able to take an IPC course of study and receive the IPC Lead Free Surface Mount Rework DVD-67C certificate on successful completion of that course. (Other related IPC short courses of study may also be added*)
