Making PCB at Home (Final)

Drilling

Drilling with 0.8mm drill bits can be a bit tricky as it's easy to break the drill bits. Always hold the drill straight and do not bend it when the hole has started. Putting a soft block of wood under the PCB provides a good base to drill into. Once you have become experienced at drilling I would recommend using Tungsten Carbide drills (FE49D) which easily break but last much longer.

1. Dry off the board and clean away the blue etch resist with PCB solvent cleaner

2. Using a 0.8mm PCB drill bit drill out all of the component holes

3. Some 1mm holes may need to be made for connectors, 3mm for corner fixings

4. Finally use a PCB rubber to clean the copper ready for soldering

So now your PCB's finished and you can start soldering the components in. You should do this soon after you have cleaned the PCB (within 1 hour) as the copper soon oxidises and becomes hard to solder onto.

The Etching

Now for the messy bit, etching the PCB to remove the unwanted Copper. Please read the warning at the top of the page as it is important to take appropriate precautions before handling the etch chemicals. I recommend you do this outside or in a shed and you must ware glasses and gloves. Keeping the etch chemicals warm (45deg C) is essential as it reduces the etch time from over an hour to about 15mins.

1. Dilute the concentrated Ferric Chloride fluid with water (1:1) and pour into the one letre glass jar and screw the top on

3. Place a sheet of news paper on a flat surface and put the trays on this

2. Fill the kettle with water and boil

3. Heat the Ferric Chloride jar in a bucket of hot water. Caution don't spill any drops and keep away from food

1. Pour 1cm of boiling water into the bottom tray then place the other tray on top
2. Put the PCB copper side up on the top tray and pour all the Ferric Chloride on top
3. Gently rock the top tray to keep the etch fluid moving avoiding spillage
4. After about 15mins all of the unwanted Copper should have disappeared
5. Remove the board and drop it into a bucket of cold water to clean off

Usefull tip: For small boards just drill a 1mm hole in the corner of the board and tie 2ft of strong cotton to this. Now put the board straight into the Ferric Chloride jar with the end of the cotton outside and put the top on the jar. Keep the jar hot by heating in a tray of boiling water and gently rock to keep the etch fluid moving. Every 5mins use the cotton to lift the board out and check progress. This method is much less messy as the Ferric Chloride is always left in the glass jar.

The Artwork

Until recently the artwork had been an area of DIY PCB manufacture which caused the biggest problems. But now by combining high quality laser printing with the Press-n-Peel PCB transfer system these problems have been solved. The first stage is to transfer the circuit layout from the PC to the special Press-n-Peel film. You will find that my projects provide Laser print files (.prn) for printing the circuit layout direct onto this film.

1. I cut the Press-n-Peel film in half for small boards so it lasts longer

2. Put the film in the laser printer so that the print will appear on matt blue side

3. At a DOS command prompt type: copy filename.prn lpt1 to print onto the film

This will produce a contact print where the black image will end up as Copper on the final PCB. Now to transfer the artwork to the Copper board by following the instructions with the Press-n-Peel film.

1. Clean the Copper board very well with the PCB cleaning rubber

2. Heat the cloths iron to 300 deg.F (Acrylic to Polyester setting)

3. Hold the film with the print in contact to the Copper and smoothly iron the film down until the print appears black through the film (about 1min)

4. Allow 5mins to cool down (or speed this up with water) then peel the film off

This should produce a clean black print onto the Copper. If you let the film move or overheat then you will find that the tracks and writing will be smeared and out of focus also the film may be wrinkled up. If you don't use enough heat or heat unevenly then the film may not stick or be dark enough. In either case clean off the PCB and try again, you should get it right after a couple of goes.

One of the most discouraging things about making a hardware project (apart from obtaining all of the components) is building the printed circuit board - PCB. It is sometimes possible to use strip board or some other pre-fabricated board but more often than not the circuit complexity and performance requires a proper PCB to be made. The good news is that due to improvements in printing and processing technologies it is now relatively easy to make inexpensive high quality PCB's at home.

WARNING: Making PCB's requires the use of Ferric Chloride (FeCI3) which is corrosive so avoid skin and eye contact. Remember safety first use glasses, gloves and protective overalls. Ferric Chloride is also very good at distorting cloths weeks after you think you have washed it off. If you do get any on your skin then wash it off immediately with lots of water and soap.

The Shopping List

This is the minimum things you will need:

1. Access to a PC with a Laser printer eg: HP Laser Jet

2. Cloths iron

3. Kettle

4. Water bucket

5. A one litre glash jar with plastic screw top (biscuit jar)

6. PCB hand drill with 0.8mm and 1mm drill bits - FR84F, QY64U

7. Copper-Clad fiberglass board - WF40T

8. Press-n-Peel PCB transfer system - AB15R

Microcontroller overview (Final)

Designing a Circuit

First, Think of what inputs and outputs your circuit will have: switches, sensors,lights, motors, etc. Then you can determine the power requirements. For simplicity, our circuit uses batteries, but a wallwart with a voltage regulator is more reliable.

Next, determine how your inputs will interface with the microcontroller.Some pins take only digital inputs. The general rule for this is that powerbrings the voltage up and ground draws it down. To make a button that changesan input pin from 0 to 1.

Some micro pins take analog as well as digital inputs; you can feed these fromanalog sensors that produce a range of electrical values. For example, a potentiometer'sknob changes its resistance, which changes a voltage fed through it. Connect a pot to a pinthat works as a ADC converter and the micro will convert the current position of the knob into a number you can program with.

An LEd will light up directly from a micro's output pins, but things like motors need more current. You can supply this by connecting an output pin tothe base of a transistor that has a higher current runing through it. Motors may generatevoltage spikes that can damage your chip, but a diode running in reverse across the transistorwill protect the circuit.
Once you know which sensors connect to which types of pins, you need to study your microcontroller's datasheet.As with most micros, pins on the PIC12F675 perform multiple tasks, and you set resisters in your software to tellthe pins how to behave in the resisters table from the PIC12F675 datasheet on Microchip's website.

Microcontroller Programming Hardware and Software

To Program a low-level chip,you need three pieces of hardware, a PC, a hardware programmer with communication cable, and the target circuit that you'll plug the microinto. You'll also need some software.

1. PC: You need at least a pentium III PC. It is better if it goes throua windows platform. Coz, almost all of the softs are windows based. But make sure that it has a parallel port.

2. Hardware Programmer: This is what you plug your chip into in order totransfer the program from PC. Traditionally, you then remove the chip and placeit in circuit, but some hardware progremmers support in- circuit programming, which lets you burn chip in place.

tutorial (click here to download)

3. Target Circuit: If you're just starting out with microcontroller programming, you can experiment witth a demo board. These are PCBs with a space to plug in your chip and various input and output devices such buttons, LEDs. Using these board will help you for running demo.If you have standalone circuit idea in mind, the next step is to build your own. There planty of circuits published online, andyou may be able to find one that's close to your need.

4.Software: In addition the hardware, you need to put together your softwaredevelopment environment. This will include the text editor where you writeyour code, a compiler, the software that drives your hardware programmer andmicro simulation and debugging tools.You can get a lot of such in web. Try any IDE to get better look.

Microcontrollers are small computers, all on one chip. The chip carries a central processing unit,program memory,data memory, and input/output (I/O) pins that can connect the instructions in theprogram memory., which tell it what to input and output to the pins.

Programming The microcontroller means writing and storing these instructionsin the chip's memory. The microcontroller speaks assembly language, which containsof binary instructions. You can use it but people prefer to program in C coz it is easier to understand.

Low-Level microcontroller VS. BASIC Stamp Module

First, Decide whether you want to use a low-level microcontroller or BASIC Stamp ModuleInexpensive low level chips (a.k.a. PICs), from Microchip or Atmel,require additional hardwaresoftware and effort. BASIC Stamp modules from Parallax and Netmedia are easier for beginners but pricer.BASIC Stamps combine their microcontroller with oscillators and other components into one.

Easy-to-program chips tell circuitry to do what you want

Press a button and a light flashes a pattern. What makes it flash?It seems like there's a tiny monkey in there flipping the switch.It so, many household items contain these tiny monkeys. They'rewhat send the infrared(IR) codes out of our remote contols andthen decode them in our televisions. They run our washing machinesand toasters. These tiny monkeys are microcontrollers, and you can train them to help you in your projects.
