The oven will run the entire reflowing process automatically, in the very last seconds you will see the reflowing of the solder happening through the window. Don't put the boards in before the oven has been preheated! Then place the PCB(s) and close the drawer. The oven will now heat up to 170 degrees and then it will beep when it's ready for the boards. If some pad have very little solder paste you can add a little more manually. Is there a nice thick layer of paste on all the pads? Now you can remove the stencil carefully and place the components. If there's too little solder, the reflowing process won't work properly. Ideally you want a good amount of solder on the pads. Just put the blobs and then smear it out with a piece of plastic or a ruler. It can be tricky to make the leadfree solder paste stick. Applying the solder pasteĪpply the solder paste to the pads. Preparing your board for the reflow oven Adjusting the oven trayĪdjust the oven tray with the hex key, make sure you can easily place and remove the boards. Place the stencil on your boards and make sure the holes are neatly aligned with your pads. On the machine interface, go into > Menu (until you see "unsetup") > Condition (use the up-down arrows) and then go into > Force and > Speed to adjust the settings. Set the speed to 1 cm/s by goin into Menu > Condition > Speedįorce is probably lower than normal, 70 gf over 1 cm/s seems ok as a starting point. The only thing that might be different is the speed, because you are working with small traces. > Window > Extensions > CutStudioPlugin Follow vinylcutting procedureįollow the vinylcutting procedure as documented here. If you cannot see it, you can also find it under Go back and make sure everything is on only one layer as singular shapes. If not: there’s still hidden layers in the design. When the drawing is clean, press the big button of the Roland Cutstudio plugin to send the design to Roland Cut Studio for cutting. You can easily switch between fill and outline with this toggle button with the arrow. Go deep in, select the singular shapes, copy and then use CTRL + SHIFT + V to paste in place on the first layer. These image traces are often very nested and you need to un-nest them. Ungroup and release compounds paths unless you get to singular shapes. Don’t move any lines or change any sizes! Ungroup and ungroup some more If it doesn't show automatically: > Object > Image Trace > Make. Run an image trace as a Black and White image and Expand. Select MONOCHROME and use 1000 DPI so it doesn't scale. Protoflow: soldering with the reflow oven
