Kameleon

Thank you for purchasing the Project Kameleon Headphone EQ / Docking station. This kit requires minimal

electronics and soldering knowledge. The layout is easy to follow and setup is a snap! Please make sure to follow

the instructions outlined in this guide and you will be enjoying your Kameleon in no time . First, lets go over the

tools and items required for your build which are as follows :

Required Assembly Tools:

- Soldering iron, 25W minimum – Variable temp soldering station preferred with 1.5 – 2mm wide chisel tip

- .032 diameter 60/40 or 63/37 Tin/Lead solder is recommended. Lead free is difficult to work with and not recommended

- We specifically recommend Kester 331 water soluble flux solder, available on our website for purchase under (Parts – Buy)

- Magnifying glass (recommended but not required)

- Rubber Gloves (recommended but not required)

- 3M Green or Red Scotch Brite (recommended but not required)

- 3/32

Allen Key

- Flush cuts

- 90%+ Isopropyl alcohol (recommended but not required)

- Paper Towels (recommended but not required)

- Digital Multi Meter (DMM or DVOM)

Before You Start Soldering:

Prep work needs to be done. Wash your hands thoroughly and dry. Put on the recommended rubber gloves and scrub down

the PCB (circuit board) on both the front and back side with 90%+ isopropyl alcohol to clean any residuals off of the board

from manufacturing. Once the board has been cleaned, set it on a dry paper towel out of the way. Try to use the rubber

gloves during the entire assembly process to keep oils off of the board and solder joints.

Proper soldering is key to a quality final product. If you are new to soldering, here are some basic guidelines to

follow. It would be wise to buy a copper project board and a few cheap resistors or other components to practice

with before starting this project.

Soldering and Solder Joints:

- For best results and maximum conductivity of any component, Wipe each wire lead down using Scotch Bright. Only one

or two passes are required, making sure all of the surface has been cleaned. This removes oxidation or any other build up

on the metal that has accumulated over time. Once cleaned, it is a good idea the further clean the wire leads with 90%+

isopropyl alcohol. Make sure all alcohol has evaporated prior to soldering as alcohol is VERY FLAMMABLE.

- Do not use to much or to little solder on each joint. See images below to get an idea of what you should be looking for

- The idea is to heat the pad and the component wire lead quickly and efficiently so that solder flows to each equally .

Wetting the tip of your iron with a very small amount of solder will aid in quickly heating up the pad and wire lead .

- Having to heat a component for long periods of time, especially capacitors or LED s is NOT a good thing. When soldering

capacitors or LED s, heat them only long enough to ensure a quality joint and let the unit cool down before soldering the

second lead.

- The solder joint should look bright and metallic. A dull or dark gray looking joint is referred to as a

cold solder joint Cold solder joints may not pose a problem initially, but can show up later in the amps life.

- After every solder joint, make sure to clean the flux off your soldering iron tip with a wet sponge that should be

provided with your soldering iron kit.

CUTAWAY OF A VIA AND SOLDER PAD

PRIOR TO SOLDERING:

VIA / HOLE

PCB

CUTAWAY

PROPER SOLDER JOINT:

- Solder is bright and shiny. It is curved

smoothly starting at the edge of the solder

pad until it reaches the lead from the

component

- Solder should fill the via and flow through

the board slightly. It is ok to add solder to

the top side of the board, however it is not

required

LEAD

IMPROPER SOLDER JOINT:

- A large blob of solder, often dull in color is

not desired. The solder may not flow into

the via hole and cause a poor connection

or failure later in the amplifiers life.
