Strife Posted November 12, 2015 Report Share Posted November 12, 2015 Hey guys! I am conducting some research on pick and place (pnp) machines and thought I'd ask the best around. For those of you who don't know, a pnp machine is a manufacturing tool which can very rapidly and precisely pick up and place small surface mount electronics onto a circuit board, where they can be reflow soldered. For fellow hobbyists/professionals such as yourselves, what are your thoughts on the concept of a desktop pick and place machine, designed for at home use? What are your thoughts on current pick and place machines in the market such as NeoDen? If you do own a pnp machine, which brand, and what are your thoughts so far? What kind of projects do you/would you use it for? If you would like one, what has stopped you from purchasing one? Are there certain requirements you are looking for before purchasing?If you do not want one, why? Do you feel the value added by a pnp machine justifies the cost which can be anywhere from $2000-$6000?All responses and opinions are welcome!

HarryA Posted June 4, 2020 Report Share Posted June 4, 2020 You may find some useful information here. If you need more help come back here. https://github.com/openpnp/openpnp/wiki/Setup-and-Calibration%3A-Bottom-Camera-Setup I worked for a company that made PnP and Through-hole machines but I only worked on the Through-hole machines.

Zahid Gul Khan Posted June 5, 2020 Report Share Posted June 5, 2020 Thanks HarryA for reply, I have visit this but its in JAVA, I wrote my own software (mean GUI) in C#, I just need basic example on rotate component when its angle is not in right position (please don't mind my English)... thanks again.

HarryA Posted June 5, 2020 Report Share Posted June 5, 2020 There is information here on Visual Servoing that maybe helpful; particularly the numerous references at the end of the article. https://en.wikipedia.org/wiki/Visual_servoing If you look at a bmp file of a smd image like this one (I could not find an image of the bottom of a smd). You can see the white background as FF FF FF and one scan line across the component highlighted. So in theory one could find the four corners and calculated the rotation and any x y offset. In bmp files the image is inverted. If you only need the rotation then only part of one edge would be required to calculate it I believe. smd compoint.bmp Zahid Gul Khan 1 Quote Link to comment Share on other sites More sharing options...
