What are the steps in the process of SMT manufacturing?

Surface-mount technology (SMT) refers to the assembly of electronic components using automatic machines that install components on the board’s surface. Moreover, this board is known as a printed circuit board, or PCB. When it comes to electronic assembly, SMT is the most popular method in the industry. JLCPCB is offering very attractive rates for PCB manufacturing and assembly. They are willing to produce 1-4 layer PCB for as low as $2 and additionally, you can get free PCB assembly once a month. This is a great opportunity to check Continue reading

PCB Assembly Services: Step by Step Guide for Best PCB Assembly

A PCBA (Printed Circuit Board Assembly) is a board that has been soldered and mounted on the PCB and can now perform the electronic function for which it was created. Printed circuit board assembly is one of the most critical processes in PCB production. Moreover, it includes all of the components needed to construct the PCB. SMT and THT are the two ways of constructing a printed circuit board assembly. Continue reading

What are PCB stencils? A Step by Step Guide for Beginners

A PCB Stencil is a sheet of stainless steel with laser-cut apertures that we have to use to apply solder paste to a PCB board to insert surface mount components. The PCB stencil has the use to apply solder paste to specific areas on a bare PCB board. So that components can be precisely fitted and aligned. An SMT stencil’s main purpose is to transfer solder paste to a bare circuit board. Every surface mount device on the board has an aperture created by a laser-cut stainless steel foil. The ideal size of the stencil aperture is to fit the PCB’s land area. With a standard stencil thickness of 0.125mm, a pad to the aperture aspect ratio of 90 percent to 100 percent is the best one. PCB stencils are made of metal or polyimide, which is commonly useful for thin sheets. Metal (usually stainless steel) stencils are best for producing a large number of prototypes. Stainless steel stencils enable more precise aperture creation. Continue reading

The Benefits of Multilayer PCB

Multilayer PCB introduced, in which connections or wirings are separated across multiple PCB boards (called layers), laminated, and glued together to keep them isolated from one another. Consequently, any PCB having three or more layers is referred to as a multilayer PCB. In the last few decades, electronics have advanced at a fast pace. Our cell phone is now a complete computer, which is not conceivable without multilayer PCBs. Moreover, the multilayer PCB is used in advanced electrical devices. It is because it allows for the integration of a high number of components on a single board. The PCB can be categorized as under: Continue reading

How to calculate the price of a low-cost PCB?

The term PCB stands for Printed Circuit Board. It is a thin board made of fiberglass or other laminate material. It is a basic building block of most electronics today. PCB is used to mechanically support and electrically connect electronic components using tracks or signal traces. However, depending on the number of units manufactured, most PCB assembly units cost between $10 and $50. The price listed above is an approximate estimate that does not include all tools and setup costs. Moreover, the cost of PCB assembly varies greatly depending on the printed circuit board manufacturer. At JLCPCB, the assembly can be free (excluded components) with the coupon you get when ordering a PCB prototype. Continue reading

What are the ways to improve layout efficiency in PCB design?

Your electronic circuits come to life in physical form on printed circuit board design. The PCB design process uses layout software to describe electrical connectivity on a printed circuit board by combining component placement and routing. What are the environmental factors in PCB design? Many variables need to keep in mind when designing PCBs for outdoor use with an enclosure to safeguard the PCB. Temperature, dust particles, vibrations, electrical interferences, and various other environmental conditions such as rain, snow, hail, and vermin are just a few examples. For better heat dissipation, try using aluminum PCBs. JLCPCB offering them from $2 Continue reading
