Best Quality and Low Price High Density Interconnect PCB are Provided by Hitech Circuits

    In the 50+ years since printed circuits have become commonplace, the complexity and density of interconnect offered has increased markedly. For example, tracks that were 1mm wide successively became 0.25mm and 150µm, and 100µm is nowadays achievable in volume, although prudence suggests that such densities are not used for large areas. And holes, which used to be 0.9–1.2mm diameter for through-hole connectors, are now typically 0.35mm or less for vias. In other words, conventional printed circuit technology is still capable of meeting many of today’s requirements. Yet there is a grouping of products referred to as “High Density [...]

High Density Interconnect: The Fastest Growing Technologies In PCB

    High Density Interconnect or HDI boards are already one of the fastest growing technologies in PCB as it contains of blind and buried vias with microvias of.006 or less in diameter. They have a higher circuitry density than traditional circuit boards. Specialty equipment and trained technicians follow the process closely to achieve the perfect hidden via.   You can find 6 different types of HDI boards: Through vias from surface to surface With buried vias and through vias Two or more hdi layer with through vias Passive substrate with no electrical connection Coreless construction using layer pairs Alternate [...]

Hitech Circuits Introduces the Knowledge of Printed Circuit Board Via

        As is known to all, via is one of the important parts of multilayer PCB. The cost of drilling usually makes up 30%~40% of the cost of PCB manufacture.   Simply speaking, every hole on High Density Interconnect PCB may be called via.   Functionally, via can be divided into two types: firstly, used for electro-connection among layers; secondly, used for fixing components.   Technically, it may also be divided into three types: blind via, buried via and though hole. Blind via is located on the top and bottom surfaces of the PCB, deep and used for connection [...]

Some Knowledge about PCB Pad Design of the Pore Size

    In accordance with the pad is designed to meet the requirements of the smallest diameter, the diameter of at least the terminal than the welding large diameter flange hole 0.5mm.  Must be in accordance with ANSI / IPC 2221 nodes required to provide testing for all pads. Node is between two or more components of the electrical connections. A test pad requires a signal names (node signal names), printed circuit board with the relevant reference point, and test pad xy axis coordinate position (note pads in the printed circuit board test which side). SMT fixtures need to provide [...]
