Traditional PCB manufacturing involves using a multitude of equipment to complete each step. While this approach requires manufacturers to invest significantly, it enables large-scale production to be completed in a short time. However, in the early stages of a project, large-scale production is typically unnecessary, and prototyping is needed to validate designs. In such cases, starting up large-scale equipment entails the same startup and maintenance costs as large-scale production. So, is there a solution to this problem?
PCB printers offer the perfect solution. They utilize additive manufacturing to complete the entire manufacturing process. With these devices, you can convert designs into complete PCBs in a short time with just a few clicks of the mouse. This not only achieves rapid turnaround but also reduces overall manufacturing costs. In this article, TechSparks will introduce three top desktop PCB printers and help you find the printing tool that best suits your needs by analyzing their pros and cons.
SV2
The SV2, developed by BotFactory, is a desktop-level 3D inkjet PCB printer. In addition to meeting multi-layer requirements, it can also perform component pick-and-place tasks. The automation features equipped in the SV2 device enable precise control of the print head’s position and ink deposition, thereby achieving high-precision printing.
Specifications/Capabilities:
8 million (200 microns) minimum trace width
300 inkjet nozzles
1-6 layer PCB boards
Max print area of 4.6 inches x 5.5 inches (117mm x 140mm) [X/Y]
Minimum pin pitch of 24 mil (600 microns) – 16 mil (400 microns)
Pros:
Compatible with any CAD tool
Offers three product models to choose from
Meets all requirements from concept to PCBA board
Complete circuit fabrication process in just 30 minutes
Cons:
Unable to handle packages involving 0402 and 0201 components
ProtoMat S104
The ProtoMat S104 is a high-precision, high-performance device dedicated to prototype PCB manufacturing, developed and manufactured by LPKF Laser & Electronics AG. It adopts advanced numerical control technology and laser cutting technology, making it one of the most prominent desktop circuit board printer options for RF and microwave applications.
Specifications/Capabilities:
Spindle speed of 100,000 rpm
20 tool positions
