Abstract
Mesin pencetak sirkuit PCB pada dasarnya adalah mesin yang menggunakan prinsip yang sama seperti mesin CNC, dalam hal ini pemanfaatannya mesin CNC di gunakan sebagai salah satu cara alternatif mencetak sirkuit PCB, dan mengurangi penggunaan bahan kimia FeCl3 sebagai bahan pelarut PCB. Berdasarkan permasalahan yang ada, salah satu solusi yang di tawarkan adalah mesin CNC pencetak sirkuit PCB berbasis mikrokontroller AT Mega 328P. Cara kerja alat ini adalah dengan cara mengonversi hasil desain sirkuit PCB pada software eagle yang ber format Jpeg menjadi file yang berformat Scalable Vector Graphic (SVG) yaitu file berformat vektor menggunakan software Inkscape untuk di konversi menjadi G-Code, sebelum di lakukan pengerjaan sirkuit PCB di perlukan proses kalibrasi terhadap motor stepper pada mesin CNC tersebut menggunakan software Grbl. Mesin pencetak PCB di lengkapi dengan sensor FSR (Force Sensing Resistor) sebagai sensor tekanan, sensor ini gunakan untuk menentukan kekuatan bahan yang akan di lakukan proses grafir oleh mesin CNC. Pada hasil pembacaan sensor FSR di dapatkan hasil bahwa papan PCB berbahan Fiber mempunyai kekerasan yang lebih tinggi di bandingkan papan PCB berbahan phenolic paper. Serta presentase keberhasilan mencetak jalur PCB sebesar 70%,presentase kegagalan sebesar 30% dari 10 percobaan, serta pembuatan sirkuit pada papan PCB masih belum memenuhi target.

PCB circuit molding machines are basically machines that use the same principles as CNC machines, in this case the use of CNC machines is used as an alternative way of printing PCB circuits, and reduces the use of FeCl3 chemicals as PCB solvents. Based on the existing problems, one of the solutions offered is a CNC machine that prints AT 328P microcontroller based microcontroller circuit. The way this tool works is by converting the results of the design of the PCB circuit in eagle software with Jpeg format into a file format in Scalable Vector Graphic (SVG) format, which is a vector format file using Inkscape software to be converted into G-Code. So that the CNC machine can print the results according to what we want with a high level of precision. For this reason, before doing the PCB circuit, calibration of the stepper motor on the CNC machine requires Grbl software. PCB printing machine is equipped with an FSR sensor (Force Sensing Resistor) as a pressure sensor, this sensor is used to determine the strength of the material to be engraved by a portable CNC machine. On the FSR sensor readings, the result is that the PCB board made from fiber has a higher hardness compared to the PCB board made from phenolic paper. As well as the percentage of success in printing PCB lines by 70%, the percentage of failure by 30% from 10 trials. and the manufacturing of circuits on the PCB board has still not met the target.
