Rework of plated Through-hole (PTH) Assemblies (basic)

Basic (rework) skills for beginner/inexperienced solder technicians.


At the start of the training Rework of Plated Through-Hole (PTH) Assemblies (basic), we first emphasize the importance of avoiding unnecessary rework and we show how a cosmetic solution can cause more problems than it solves.

If the conclusion is that Rework is unavoidable, we will introduce the participants to various examples of Rework procedures approved by the industry. During training Rework of Plated Through-Hole (PTH) Assemblies (basic) the following topics are covered: vacuum extraction, (partial) bent and unbent DIP leads and auxiliary heating techniques for large thermal mass surfaces etc.

We also look into the details of anomalies such as solder defects, solder bridges, solder projections, and excess/insufficient solder.

ETECH-training will ensure the following practice material:
– Soldering equipment
– Flux
– Solder (Leadfree)
– Tweezers, wire cutter, wire stripper, Orange stick etc.
– Magnifying lamp or microscope
– PCB (populated printed circuit board)
– Resistors 1/4 watt
– DIP/SIP components 14 Pin
– Capacitors with spacer
– Transistors with spacer

Duration

Certification: 2 days including exam

Recertification: 1 day including exam

Challenge test: 0,5 only exam


Course materials

Each participant will receive a summary of the training. During the training, the participant will receive a copy of the 7711/21 IPC and the IPC-A-610 on loan. ETECH-training takes care of the practical materials.
