Prototyping and PCB assembly in the field of electronics industry is made possible through a process known as cutting the PCBs from their original circuits. It’s critical that if you are sanderling a certain PCB board to match with the specified enclosure or doing patch in the case where partial boards are required to connect, you take note to follow the stipulated guidelines to save the components from damaging and avoid the happening of the broken traces. This post would provide you with several tips and tricks that making PCBs cutting safer and easier.
How to cut circuit boards?
Stuffing with components involves a lot of fiddlering, and having the right tools for the job. First, gather all the necessary materials: an iron board, protection goggles, a ruler, a pencil, a hacksaw – or a rotary tool with a cutting wheel. Next, mark the cutting line on the circuit board using the ruler and pencil, ensuring accuracy. Put on your safety goggles ready prior to cutting them, for safety eyewear acts as protection from the debris. Then Following, hold the cutting tool adjacent to the marked line and apply a balanced pressure to proceed slowly and gently. After Taking down obtain some sandpaper or a whetstone for getting rid of the coarse edge. Inspect Examine the cut and ensure it is precise, adding any needed extra cut. Finally also dispose of any waste material based on the latest local regulations. Exercise extreme caution when clipping circuit boards so as to avoid grounds for the destruction or hurt.
Why do we need to cut printed circuit boards?
Cutting Printed Circuit Boards (i.e. PCBs) is required for different purposes. One Compactness is another factor that may fit considered for the board production. The idea is to fit the PCB into another reason is to separate a larger PCB into smaller. Another reason is to detach a large PCB into smaller electronic boards that will be used for small manufacturing or assemblies. In the case of PCB, cutting is often called for either to eliminate imperfect or faulty sections, or to add new and more elaborate elements. Besides, cutting is often used for the etching of the PCB’s custom shapes or special types of designs. The main reason for cutting down PCBs is saving manufacturers time and costs while bringing customers the devices to their suitability.
What are the different ways of cutting circuit board?
There are several board shops which are able to produce the same of the same PCBA, but not all of them use the same process to produce PCBA own advantages and applications:
- Manual cutting process – It is a process in which a human cuts out the PCB along the separated lines using handheld cutting tools like a hacksaw, utility knife, or shears. The manual cutting is suited for small-scale projects, by which the ability to micromanage process is provided during the cutting process.
- Score-and-snap – In this technique, the so called SC – PCB is made in the location of the envisioned component placement, normally using a specialized cutting tool or a sharp blades. When done, the clips are cut across the v score line or v cut, breaking into a straight position with no tearing. v Scoring and snapping, due to its versatility and simplicity to cut, is ideal for cutting large amounts of PCBs with only effort required in accepting more equipment.
- CNC milling – Computer Numerical Control (CNC) milling operates by using a machine that has a cutting bit rotating inside to make out a precise pattern or form into a PCB. CNC milling gives high precision and is good when it has complex designs or when the production is done in large amounts.
- Laser cutting process – the laser cutting process involves the use of a laser beam which is focused on the material surfaces to create predetermined specific paths of the desired cutting. With laser cutting you can go really quickly, be spot on accurate and do fine details. Nevertheless, it is suitable only for industrial application and could be cost-effective.
- Waterjet cutting process – Waterjet cutting is an extremely high pressure treated stream of water that has been mixed with an abrasive particles that is in order to remove the constituents in PCB. Waterjet cutter is quite inclined towards being versatile which allows it to cut through all kinds of materials such as metals and plastics with an almost cent percent precision. Nevertheless, it involved particular attention and possibly created waste water as a side effect.
How to cut printed circuit boards at Home?
Production of printed circuit boards (PCBs) at home can be realized with an easy of use conventional equipment and desire to do things with a high level of accuracy of prototype pcb. Start by scratching off the through-cut on the PCB using a ruler and pencil. Wear safety goggles during cutting, to safe your eyes from incurring any eye injury. Next, you will need to cut along the line you marked earlier using one of the cutting tools like a hacksaw, utility knife, or rotary cutting tool with a cutting wheel. Ensure that you apply firm and steady pressure while cutting. Fold back the material to eliminate any bending and uneven edges, then smooth out the edges by using sandpaper or a file. Be cautious and place your workbench, where there is a good fan. Now, you should recheck that the cut pcbs bases your expectation. DIY projects designers sparing PCBs at home demand for careful and accurate approach, however if you learn and acquire tools of tehnique, making it is no longer so hard.
What are the required tool and Equipment?

How to cut pcb board in altium?
In Altium Designer, go about cutting a PCB board by creating a shape on the board edges outline layer, which is also called a cutout shape. If you would like to create inner traces, use board planning mode in the PCB project and select the board outline layer. Then, utilize the Polygon Pour feature to sketch a sealed-to-the-end contour that corresponds to the area you would like to cut from. Double-click on the polygon to launch the Properties panel, where you can configure the layer to the board outline layer and choose the net option “NoNet” to separate the region from the circuit layout for a tin snips. The resizing and positioning of the shape (cutout) can be done by manipulating its vertices. Savoring the completed silhouette, just switch back to the normal PCB panels mode, consequently get the outputs for fabrication. Prior to the manufacturing, confirm it with your board manufacturer so they are aware and there wouldn’t be any issue during the manufacturing process. Following them will let you trace your way to good JFCB Design results with Altium Designer tools and techniques.
How to cut circuit boards for jewelry?
Making jewelry cutter board need to keep its target shape and do it preciously. First of all, take the materials like a circuit board, your safety goggles, a ruler and a pencil in your hand along with some cutting tool like a jewelry saw, rotary tool with a cutting wheel. Follow by drawing a pencil line to illustrate the pattern you want to cut on the circuit board with the ruler.
After that, turn on to the safety goggles and meticulously cut along the directions that have already been marked using your chosen cutting tool. After the cutting stage, sandpaper or a file can be used to make any of the edges you found shaggy smooth. Lastly but most importantly, spotless the circuit board pieces that would be used in the jewelry design. Well ventilated workspace is essential; please follow the safety procedures if you are cutting circuit boards to make jewelry.
What are the tips and techniques for cutting smooth pcb?
Preparing a smooth PCB involves nothing else but a careful work, suitable hardware and an appropriate methodology. Here are some tips:
- Use the right tool – Sharp cutting tools are needed for this. Choose from fine-toothed saws, rotary tools with cutting wheels, or precise knives. That’s what will ensure cutting exactly as you need.
Mark the cutting line – Draw it out with a ruler and pencil close to the correct line. Make sure that the measurements take accurately. - Secure the PCB assembly – firmly holding the PCB, then cutting. This will stop its movement, and thus, it guarantees a straight cut.
- Cut slowly and steadily – either clamp it or use a vice to hold it in place before cutting. This will stop the cutting tool from wobbling and thus cut straight.
- Use a backer board –Hold the snips straight and cut gently along the marked line. Don’t exert excessive force when sanding PCB material, it may crack with it.
- Sand the edges
- Clean the PCB assembly
Summary
In cutting printed circuit board it would be needed the precision of the materials and the right tools either two individual circuit boards just following rules and following methods. You need to use sharp tools just like mini saw or if you want rotary tools, and then you will secure the pcb just to aware and preventing of the movements, and after you will cut it slowly gently. You will mark the cutting line precisely and 100% accurately and then you will use a called backer board thickness just to protect and to support the printed circuit board. After then cutting the smooth the edges together with sand paper in order to clean finish.
