What is it?
A reflow, dry, and cure PID oven controller.
The controller can reflow ROHS lead free and PB based solder paste, it can dry parts for days at times, and it can cure epoxy and chip bonder. There are counteless more uses for a PID based oven controller!
The PID (proportional integral derivative) is a loop control equation to minimize error and drive a "plant" or system to a target state.
This controller reads from temperature sensors and has the PID control on the controller, and uses the computer software to graph the output and control the options, modes.
Who are you? and What is your experience?
I am the former CEO of The Silicon Horizon Inc. who has sold thousands of reflow controllers all over the world!! We have been in "Make" magazine before and many others. You can find our videos on youtube by searching for "the silicon horizon" or click on the link below:
We strive to produce accurate and precise temperature measurement and control.
I am now the CEO of IPHolders Inc, having worked at the US Patent Office in RF Communications, I have a bachelors in electrical engineering and alot of graduate credit and a TON of design work for major defense companies and telecommunications companies.
We use CircuitStudio (from Altium) for design and layout and 3d visualization.
We have a full lab with test equipment and are experienced in using them.
Whats great about this design? Whats new? What makes this better than the other ones?
Other reflow controllers just reflow. Our reflow controller reflows, dries and cures.
Reflowing BGA with an older controller version and software:
Curing loctite (chipbonder for a BGA) (older version controller and software)
Reflowing with our older version software and older controller:
We also support using multiple sensors at the SAME time, such as K type thermocouples, infrared thermocouples from omega engineering, and many others.
You can trigger from an infrared thermocouple, and use the PID control with it !!! this is great for having a PID based on surface temperature.
You can also trigger from the K type thermocouple.
The other sensors run at the same time and graph in realtime on scrolling graphs.
The controller is designed very well with good layout (current hardware version)
- 1.75" x 1.75" small size
- 12 bit ADC
- mini USB jack
- full ground planes
- low noise 1% regulation
- AD597 thermocouple amplifier for fast analog readings (not a slow digital chip)
- winUSB driver to work in modern OS versions such as windows 7,8,8,1, 10!! not something that will not work later on
- fast assembly language for math routines
- commented C code
- eeprom for profile and settings storage
- 6 extra IO and ADC lines to terminal blocks for later expansion or additional sensors, can use module functions on these pins as well, very configurable input or output functions
- oven PID output
- fan PID output
- reprogrammable via a programming header.
- free compiler, free IDE, microchip XC8, mplab X IDE
The windows GUI software is being redesigned to offer alot of advanced features. Not only can you dry or cure for DAYS at times, but reflowing can be done from ramp profiles or spreadsheet values.
The windows GUI software can do scrolling graphs, save screencaps, and provide output for upto 3 sensors @ one time. You can choose which sensor to trigger off of, and which sensor goes in what graph.
The windows GUI software is current work in progress and has had successful runs through it already:
Some features of the NEW windows GUI software:
- skinned GUI
- scrolling graphs with net 4
- C# code (for those of you who choose to get that reward level)
- winUSB driver implementation using windows WMI, with complete exception catching and very well written code
- screencaps graphs
- multiple graphs displayable at a time
- can switch sensors between graphs
- can trigger the PID off of any sensor you want (trigger the PID off an omega engineering infrared therocouple to get surface temp triggering!!
- can trigger from k type thermocouple
- spreadsheet profiles
- ramp profiles
- dry for days
- cure for days
- set advanced options such as PID coefficients
- audio cues for each stage (a female voice) announcing start of preheat, reflow, cooldown etc.
What kind of rewards do you have?
The rewards start with getting a controller with software shipped to you to getting FULL SOURCECODE to the windows software and the firmware so that you can make changes yourself etc to having us produce a derivative controller for you with design files and windows software changes as well.
Intended implementation (for safety and reliability)
It is suggested to use a zero crossing solid state relay overrated for your target amperage range. The output should take 3 V minimum and only draw a maximum of 15 mA (25 mA max) current on the DC control side.
House voltage (120 volts and 240 volts) at higher amperages WILL KILL YOU! you must be experienced in wiring up mains wiring and voltages in order to do this project yourself. In using this product, you agree that you have enough experience to handle the wiring and know all the safety to carry out the task. We are not responsible for any injuries caused by your own wiring / assembly.
funding to 1 month: final manufacturing of needed reward units
1 month to 2 month after funding: finalize windows software and tweak firmware.
Because of our previous experience and capability, we can delivery this quickly :-)
Thankyou all for reading this.
Risks and challenges
Since we have already sold thousands of reflow controllers (older designs) we have the experience to complete this job.
We have also significant experience in layout and design and USB integration.
Thus the risk is very low.Learn about accountability on Kickstarter
