Advantages of Laser Cut SMT Stencils for SMT Assembly

Laser Cut SMT Stencils: Surface mount technology or SMT Stenciles is the procedure of mounting the electrical parts straightaway onto the PCB surface [1]. SMT has replaced the through-hole technology technique of aligning parts with cable heads into holes in the PCB. The essential part of the SMT procedure is the covering of solder glue on the PCB. First, it is managed by screen impressing the solder glue with the assistance of solder stencils. Then, the solder glue is equally applied with the utilization of a squeegee. Laser Cut SMT Stencils are laser-cut solder glue image stencils. It is organized for hand-operated ...

PCB Design, Selecting the Right PCB Trace Widths?

Every PCB designer has a series of decisions to make PCB Design [1] as they translate an abstract schematic into a functional, reliable, and manufacturable PCB assembly [2]. Placing the components on the    PCB is usually the first step, connecting those components with copper conductors to create the circuit is the next.  To connect the components, the layout designer must interpret the circuit netlist and turn that netlist into actual copper traces, subject to constraints of both manufacturing technology and the laws of physics.  One of the most important considerations for the designer is the appropriate trace width for each ...

PCB assembly Pre-Reflow FAI

First article inspection (FAI) prior to SMT assembly [1] is a design verification methodology that provides a reported verification and validation of details of a product on the shopfloor per its manufacturing procedure and requirements. There are various ways to perform FAI, from both supplier’s and customer’s side, making it a very dynamic process. This means that each organization can tailor its FAI method to benefit itself and consequently, its customer, yet maintain rigid performance standards at the same time. FAI involves qualitative and quantitative measurement. FAI is also highly effective since it can potentially fulfill process validation requirements of ...

CONFORMAL COATING

What is Conformal Coating? Conformal coating is protective chemical material coating applied after the final SMT PCB assembly [1] or through-hole assembly process. Coatings are comprised of 5 different types, Acrylic, Epoxy, Urethane, Silicone and Parylene resins. Applying the coatings to a PCB board assembly [2]can be done by hand spray, robotic spray, brush or dipping. The coating acts as an additional dielectric layer that provides protection due to environmental and mechanical stresses, such as thermal extremes, chemicals, dust, salt fog, abrasions, and moisture. In a PCB assembly [3] that has close spacing of conductive pathways or close ...

Printed Circuit Board thickness considerations and requirements

How Do You Select a Printed Circuit Board Thickness? Selecting the correct PC Board [1] thickness for your product requires balancing of three often competing aspects of the design: manufacturability, electrical performance and mechanical constraints. Modern PCB fabrication techniques at PNC give the PCB designer great flexibility in specifying the PCB lamination stack-up and gives them the option to design a PCB in a thickness other than the typical choices of .031”, 062” or .093”. Manufacturing considerations in selecting a PCB thickness To understand how to specify PCB thickness, it is important to understand how PCBs are fabricated. Most multilayer PCBS from 2 ...
