LED aluminum PCB design

LED Aluminum PCB is composed of the circuit layer (copper foil layer), thermal insulation layer and the metal core layer. Circuit layer require great current-carrying capacity, thus should use thicker copper foil and generally the thickness is from 35um to 280um; Thermal insulation layer is the core technology of aluminum PCB, it is usually made up of special ceramics and fill special polymers, with small thermal resistance, good viscoelasticity, and has thermal aging ability, and can be able to withstand mechanical and thermal stress. Thermal insulation layer of IMS-H01、IMS-H02 and LED-0601 and other high-performance aluminum PCB are using this technology, [...]

How to prevent warp on printed circuit boards?

The bow and twist issue on Printed Circuit Board can cause components and parts registration in PCB assembly process, when handling with SMT or THT, if the component pins are positioning not trim, which will bring a lot of difficulties on assembly and installation. IPC-6012 standard define the maximum bow and twist 0.75% on circuit boards of SMB—SMT, other PCB bow and twist is generally not exceed 1.5%; Electronic assembly plants allow bow and twist (double/multilayer PCB) is usually 0.70---0.75%. As a matter of fact, many rigid PCB boards (board thickness 1.6 mm) require bow and twist is less than [...]

A Look Inside The PCB Design Process

Printed Circuit Board (PCB) Design, also referred to as PCB Layout, is the first step toward a successful PCB assembly. At this stage in the PCBA Manufacturing process, an engineer has decided the circuitry of the printed circuit board, and the layout can be designed.     Using PCB design software, the designer will design the component placement and routing of electrical connectivity on the printed circuit board. From RF/Microwave to High-Speed Designs, the Hitech Circuits design team can tackle any type of technology you require. Hitech Circuits designs with manufacturing in mind, meaning a smooth transition to production. Once [...]

Five knowledge points of PCB Design technology–Hitech Circuits Co., Limited

1: Print line width selection: The minimum width of the printed line is related to the current flowing through the line: the line width is too small, the resistance of the printed line is large, and the voltage drop on the line is large, which affects the performance of the circuit. The width, the wiring density is not high, and the board area is increased. In addition to increasing the cost, it is not conducive to miniaturization. If the current load is calculated as 20A / mm 2 , when the thickness of the copper foil is 0.5MM (generally), the [...]

DESIGNING FLEXIBLE PRINTED CIRCUIT BOARDS( Part One)

A Flexible PCB is defined as an arranged pattern of integrated circuits and components that uses flexible based materials. Here, the same components used to produce rigid printed circuits boards might be used to fabricate these flexible electronic assemblies, but they should allow the flexibility of the board during its application. Some of the advantages provided by flexible PCBs include; low mass, greater reliability, high ductility, and space savings. But also, inventors/designers must be ready for their complexity and complications. Except for the fact that the designer must be accountable for the mechanical complexity related to a flex circuit, there’s [...]

DESIGNING FLEXIBLE PRINTED CIRCUIT BOARDS (Part Two)

High-density-Interconnect (HDI) Flexible PCBs When there are no adequate options provided by typical flexible circuits, HDI PCBs come into play by incorporating fine features like micro-vias, better layout, construction, and design. In addition to the above features, other features include; highly dense flex circuitry, Increased functionality, and smaller form factor. HDI technology offers improved electrical performance, access to advanced IC package use, and better reliability though it makes use of thinner materials.   Benefits of Flex Circuits As for a ribbon cable or discrete wiring replacement, customized repeatable routing supplied by flex circuits trails all through the assembly. Because of [...]
