Soldering Induction

This induction has been separated hand tools induction to better cater for the needs of the public. The soldering induction is now focused on the different aspects of soldering and introduces users to a the different types of soldering as well as covering on what tools are recommended to use while working on a project requiring soldering.

The changes will take effect after July 2017 during the first half of the 2017-2018 Core Workshop program.

Summary

Your Setup

Soldering Irons; Cheap vs. Expensive

Cleaning; Brass Wire pad vs. Slightly Damp Sponge

Wire; Solid and stranded wire, 22AWG, Red, black + random color

Solder; Thin vs. thick

Desoldering braid

Lighting

Helping Hand

Ventilation / Extraction

The Basics

Hold the iron Like a pencil but further up

Never touch the metal part of the soldering iron

Never leave or rest the soldering iron on a table, always use a soldering iron holder. Iron is very hot and things can easily catch on fire

Don't eat while you're soldering, solder contain some nasty stuff which you don't want in your body

Always use ventilation (Fan, draft, etc)

Eye Protection is not required but highly recommended

Always wash your hands after soldering

While you're soldering

Tinning

Cleaning

Types of soldering

Wire soldering

Through-hole soldering

Surface mount soldering

Whats a good solder joint look like? here's Seed Studio's take on what you want and what you want to avoid

What do you do if it doesn't look right/

desolder using you desoldering braid“ or solder sucker but remember to not put too much heat in and fry your components (give the componets a rest tool cool off ) Notes**

Visit the ESO’s in the Security office near the museum and pick up a hot work permit for the duration of the induction (plus half an hour)

Ensure that the soldering kits contain the necessary tools and that the irons have usable tips before the start of the induction

Ensure induction paperwork has been printed (Programming pod in staff area) and pens that can be found in the hurst behind the facilitators desk in the fab lab.

C51 Clock Kit Assembly

Capacitor (C1) and transistor (Q1). Make sure to put this in the correct direction.

Piezo Buzzer (8550). Match up positive side with marks on board.

Capacitors, Large (C4), Small (C2,C3). Legs go in either way.

Resistors (R1, R2). Go in either way.

Momentary Buttons (S1,S2). Point legs out to the left and right. Quarts Oscillator (Y1).

Power Input Jack (J1). Make sure to face inputs outwards.
