Have you ever used a PCB engraving machine? [Copy link]

As the title says, the school wants to purchase a circuit board engraving machine for teaching and training students. It should be able to process commonly used SMD component printed circuit boards. I would like to ask if any netizens in the forum have used engraving machines and can recommend a suitable model?

I have never used the corrosive agents used in school.

I have used similar engraving machines briefly. The accuracy is generally acceptable. The main problem is that the selection and operation of the tool head are more troublesome. The vias of two-layer boards are not easy to handle. I have seen that the use of galvanometer laser engraving on the Internet should be very expensive.

Thank you. We have not used it, but just heard about it, so we have no idea.

Several parameters should be considered: effective stroke, length, width and height, from how many millimeters to how many millimeters, parallel port type, what operating system is supported, what control software is used, motor power, noise level, and continuous working time

Yes, these factors need to be considered. Thank you!

You can find this on online shopping platforms, but the efficiency of engraving PCB is too low. Considering the depreciation of equipment, the price may not have much advantage. Now the cost of online PCB proofing is not high, and a universal board can be used for simple circuits.

Haha, it is used in school, regardless of efficiency and price. I have found a suitable one. Thank you!
