Hello, I am going to present a problem and a solution for the operation of the induction hob.
The client indicates that the plate has a problem on fires that do not work right.
First we see the plate.
It is noted that one of the fires and had an accident, but it is not the case, although this fire break if it works, which correctly are not going right.
We dismantle the stove and see behind the features.
Below the board model shown is the F13-4B.
It is observed that is placed on brand and plca works but does not heat, check the toutch apparently can say that it works at least with the fires on the left. We must assume that the fault is the power part and not the control. To do this and to rule out the problem, disassemble the hob, removing the side screws that attach the touch control and the frame as well as the side that separate what the board electronics.
See cables that coils which are induction and these are below about bind cartons with aluminum.
In this case, no images were taken vitro, but this is an example of three fires to understand the concept.
We disconnect the coils and found the plates for each side.
You must have two plates like this, the image of the plate itself is under discussion. Because we knew that if they worked two fires that were the left side, then exchanged the plates as they are identical and both fires are the same side as the other.
Provisionally we assemble and realize that work, therefore it completely rule out the control panel and power. Looking for information on the plate we found a French operation manuals plate in French, but now as much as I seek can not find.
I found several flaws in these glass ceramics respect to induction, especially heat, is the problem with heat dissipation, which is usually not the right and dry capacitors. So this problem before we get to check capacitors with a capacitance meter.
After checking we realize that everything works all capacitors and resistors, measure continuity to view the tracks, check the Graetz bridge, and power transistors. But these checks continuity we realize the following detail.
Graetz bridge is loose by heat welding heat and therefore does not support breaks, for nothing soldering iron and tin. During these operations the other plate also is broken and no longer works no fire, so we set up the newly repaired and see that it works, we took the other and see the same error but in another area of the Graetz bridge.
I attached some links which often fail induction hobs.
Today I will explain how to put the Kapton tape on the baseplate of a 3D printer.
We need the following materials:
Alcohol to clean, paper towels, plastic spatula, cutter, a wooden board, spray soapy water or spray, a tupperware and Kapton tape.
The procedure, first sprinkle alcohol on the baseplate.
Second scatter with kitchen paper and clean all baseplate.
Third sprinkle with spray soapy water around the baseplate. We put it on the Tupperware.
Kapton tape stretched his is with the help of another person.
We support the belt in place, you will wrinkle if you do some solos, but do not worry.
With the spatula removed the wrinkles and bubbles.
We cut with the cutter and continue removing bubbles.
When we finish we remove the tupperware below, we turn and we will cut the excess.
And we're done.
Brands that can be seen are scratches on the baseplate, try to avoid using the spatula may cause deformation at the base of your objects.
In this exercise we will create a Arduino UNO PCB from scratch, we will be able to customize it as you like. We will all, from the schematic through design, component creation, sourcing, creating the PCB, put rivets and welding components. We tried realiazr programming board with Atmel Studio programmer, but there were compatibility issues bookstores and Arduino, so this step can not do it now, if you can do it will post later.
Well to start with all this we must know what an Arduino UNO.
Arduino UNO is a microcontroller plate hardware is free, that is, we can make copies of it because it was invented as an educational support. It incorporates a reprogrammable microcontroller and a series of pin female (which are attached to the E/S of microcontroller pin) for connecting there easily and comfortably different sensors and actuators.
When we talk about hardware board, we are referring specifically to a PCB (Printed Circuit Board). The PCB surfaces are made of a nonconductive material (typically fiberglass resin, ceramic or plastic) laminated on which conductor tracks (copper) materials appear. PCBs are used to electrically connect, via the conducting paths, different electronic components soldered to it. A PCB is more compact and stable way to construct an electronic circuit.
All Arduino microcontrollers are the type AVR architecture developed by ATMEL. Mainly Arduino Uno has the ATMEGA 328P, and also accurate to schedule the ATMEGA16U2 USB, a USB to TTL converter.
In this picture we can see the step ATMEGA328P and identify ports for programming.
Then the ATMEGA16U2.
Once the introduction of what the microcontroller, we need to know what leads a microcontroller system inside.
We have understood what we will do, let's start making our Arduino UNO as REV.3, so we need the schematic we can consult the web
With the Proteus software we carry out our schematic. As stated are other entries of how a circuit is done with Proteus, I leave the link so you see it.
Once you have connected components well, we're going to ARES.
If we want to do with the size it is Arduino Uno to place him shields, we must continue indicating the next image.
This will be the view of the plate.
Once our board need to buy components. As we have learned to make the footprints of the components and put the price should not change much, while suppliers do not sell a single component, and must buy minimum lots, I attached the web where you can make purchases.
In the part of Bill of Materials will leave everything it takes to make our Arduino RS as references are those that have put. I attached a cut image as displayed.
Once they reach the components, we will get to work for the board, in Proteus ARES have an option called Generate Gerber.
We see this message.
We say yes, because we have ensured that we have not left any clues unbound or no potential conflict between tracks between tracks or between components.
It will do the test.
And this should appear and click close, if not put PASSED must correct the error.
We will get this screen and choose according to what we will use as a machine for our board. In my case is CNC so we will choose this.
We chose the location and keep it in a .ZIP, press ok and our archive should leave it.
We get the file to a pen and go to the computer that runs the CNC. The model is as follows.
The protocol we have is us a folder with students on the computer in which consist our plates and a excell document the use we give to the milling and drilling, but later I show the type of drill.
Although we have done what the Gerber, we must tell our CNC parameters that through Circuit Cam program transforms them into a document type that if you understand the CNC for that I leave a video explaining how.
Then we have a video of how to use the Board Master and put strawberries and drills, is now her time to explain that strawberries have given us for the plates are essential and are Orange 0.2mm 8mil for tracks to be skirting finer things and the abode of 1.00mm is the END thousand which is to finish and leave things ready. Which comes with green border are bits of different sizes and then we have one that is cut is called yellow Contour router.
A video of how to get bits and starts the process of making changes via attached.
The next step is to perform milling botton but clear before we know if the drill is up for it we go to the plate and choose with left mouse button a small part of a track that is little conflict and give the chosen tool in the photo.
We give Start and hope to do the selected track, we take the microscope and see.
If we see that the track is in the regulatory measures and are isolated from each proceed forward as shown in the video, if you had the following must regulate to come down here deepen strawberry or strawberry much to climb. One little penetration failure strawberry attached.
We go to the CNC and give roulette drill. Do this until you get it right.
Now enjoy the video of how to do the milling botton.
After milling botton we have to flip to the plate and do the milling top. Video of how the operation is attached.
Once made the top milling cuttingoutside have to do is make the cuts to remove the plate as will be explained later.
Para finalizar tendremos que apagar la CNC, apagar el ordenador y aspirar las virutas de la zona de trabajo dela CNC.
Once we have left to do off the cookie, for this we follow the next video.
Attached are photos of several plates.
Now after making the PCB is put track changes that are made riveting. Attached are photos of the process.
In the next picture we do it is support him and then turn around and drive home to the punch.
After riveting the entire board we have to take the components and soldering, as I have no explanatory video I will attach a video from my partner John Biondi as SMD welding.
And as a final picture welding plate is attached.
