PCB Stencils, also known as SMT (Surface Mount Technology) templates, are a type of specialized tool used in SMT processes.
Printed circuit boards (PCBs) play a critical role in connecting and supporting electronic components in modern electronic products.
It is important to use DFM (Design for Manufacturing) methodology in the design of PCB/PCBA (Printed Circuit Board/Printed Circuit Board Assembly).
In the process of electronic product development, Design for Manufacturing (DFM) plays a crucial role.
Design for Manufacturing (DFM) is an important part of the product design process, aiming to ensure the feasibility and efficiency of the product in actual manufacturing.
There are instances when PCB/PCBA designers and manufacturers face communication challenges, leading to problems during the manufacturing of printed circuit boards.

Circuit board prototyping, is a process of PCB manufacturing experimentation. This process offers a pre-production analysis of circuit boards are to be produced.
VayoPro-DFM Expert software is an intelligent design for manufacturing/assembly analysis tool that helps accelerate new product introduction.
During SMT programming, process engineers usually need to manually adjust the rotation of some special components.
During PCB design, some common defects, such as TH component’s lead diameter, plated hole and pad mismatch, tend to occur on through-hole (TH) components.
The importance of design for manufacturability (DFM) has been extensively stressed in recent years.
SMT stencil design is an essential step of SMT procedure and determines the soldering quality of PCBA.
Most of quality issue during manufacturing is due to the design omission.
Ball grid array (BGA) is a type of surface-mount packaging used for integrated circuits.
SMT machine programming is the first step of surface mounting as well as an essential part.
Have you ever troubled by the fact that you paid good money for a software, while you use it just for a few times.
Surface mount technology (SMT) is an essential part of PCB assembly, and the efficiency of SMT greatly affects the efficiency of quick turn PCB assembly.
For quick-turn PCB assembly, a ready-for-manufacturing PCB design is a critical.
Quick turn PCB assembly is getting its importance as the industry 4.0 is becoming a trend.
Flying probe test is a common method implemented for PCB reworking. Engineers usually want to use flying probe to conduct a comprehensive OPEN test on all nets, hoping to find out open circuit fault of PCB route.
FABmaster, S.A, incorporated in 1994 (about 28 years ago), was a leading worldwide supplier of CIM Automation software for board assembly optimization, incircuit & fixtureless test & inspection.
DFM/ DFA analysis is an essential process for concurrent design. Are you still looking for a software to facilitate your DFM / DFA analysis?
PCB testing is a critical process of PCB manufacturing. It is to test the qualification of each component, package, etc. on PCBA by specific test equipment, program and methods.
Flying Probe Test (FPT) is a kind of In-circuit Test (ICT), using mobile probe to test the printed circuit board (PCB).
PCB Stencil design is the core process of SMT (Surface mounting technology). Stencil’s quality concerns 70% PCB manufacturing process, including silkscreen printing, SPI, SMT, reflow welding, etc.
Visual work instruction software or digital work instruction software is becoming indispensable for shop floor of SMT factory to create digital step-by-step instructions for assembly line.
Trending towards the Industry 4.0, the market puts more emphasis on the shorter time to market, higher quality and lower cost.
VayoPro - Test Expert could generate test program for leading In-circuit test (ICT) equipment like Keysight (i3070, i1000), Teradyne test station (GR 228x), TRI (TR518, TR5001, TR8001), Spea (T300, 3030IL), Seica (Next), …
An offline programming software tool is very critical for programming of PCBA flying probe test, VayoPro - Test Expert is a powerful tool you shouldn’t miss.
As we all know that PCBA testing is one of the most important procedures before mass production of the new product, it’s not practical to run every test moneywise and timewise.
Along with the development of electronic manufacturing industry, DFT (Design for Testability or Design for Testing) has showed up its importance of guiding the designers to improve the testability of the designed circuit.
Design for testing or design for testability (DFT) is a critical technology to ensure the accessibility of manufacturing test.
A CAM software tool for engineers should understand the real need of front-line engineers and the process flow.
The core of CAM (Computer Aided Manufacturing), is computer numerical control, referring to the process/system of using computer in all operations of a manufacturing plant.
Field process is essential for the fabrication of PCBA product.
An Engineering Change Notice (ECN) is a document authorizing and recording design changes throughout the prototyping and life-cycle phases of a product.”
In the context of intelligent manufacturing, intelligent tools are becoming a necessary aid for PCB manufacturability analysis.
The tide of Industry 4.0 has led the development of electronic manufacturing into a new era, in which PCB manufacturers have to find another way out.
DFX indicates the design dealing with every process of NPI cycle.
Along with the goal of Industry 4.0 comes the concept of DFX. It has been questioned on “what is DFX?”, “ What is for?” and “Why DFX?”.
The trend of Industry 4.0 is pushing the factory to develop toward a more intelligent future.
As the manufacturing industry are stepping forward the Industry 4.0, smart factory and flexible manufacturing, DFM or design for manufacturing has won great popularity.
It may not be strange for SMT (Surface Mounted Technology) engineers to programme for panelization with multiple & free-angle boards.
Currently, most programming process of PCB panelization requires input of measured data, such as outline data, matrix offset, etc., and this method tends to cause deviation of coordinates of component mounting location, thus causing incompliance during boards mounting.
Kelvin Four-terminal sensing, also called four-wire sensing or four-point probe method, is an electrical impedance measuring technique, which uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurement than two-terminal sensing.
