Introduction: Overview of Laser Prototyping Technology
Definition and Development History of Laser Prototyping
Laser prototyping technology is a cutting-edge manufacturing method that uses precise laser beams to cut, engrave, and drill materials to rapidly create high-precision PCB (Printed Circuit Board) prototypes. This technology emerged in the 1970s and has gradually found its
In the manufacturing of electronic products, the printed circuit board (PCB) plays a vital role, and its surface finish has a direct impact on the performance, durability, and cost of the final product. PCB surface finishes are used to enhance solderability, prevent oxidation, and ensure stable electrical connections. As technology
With the rapid development of electronic communication technology, in order to realize high speed and high fidelity transmission of signal, more and more high-frequency circuit boards are used in communication equipment.The dielectric materials used in the high frequency board have excellent electrical properties and good chemical stability, which are mainly
PCB Depth control routing technology is the stepstair or groove shaped by partial routing in printed circuit boards(PCBs) manufaturing.It have great advantages in PCB assembly as the special shape of depth routing.
Use the step stair of PCB edge make card slot is favor for PCB fixed and installation.
It
The high in difference of heavy copper PCB is easy lead to oil float away,fake copper exposure,oil uneven when printed solder mask if controlled unwell.This article analysed and improved this problem through line mask printing area, solder mask opening of silkscreen ,printing lay up time and printing method.
The traditional process
Pre-treatment--->solder
Flex-Rigid PCB is mix FPC and Rigid PCB,followed special requirement and press them together. It’s compatible both of FPC and Rigid PCB advantages.Enginner always use 2 rigid PCBs,a flex pcb and a switch to connect them before Flex-Rigid PCB be published.Flex-Rigid PCB have strong resistance for bad application environment,it’s good
It’s important to know factors affecting of PTH throwing power to electronics products, then improve high aspect ratio for facilitating productivity.it’s good for electronics products reliability,reduce fabrication cost,improve productivity.
PTH
Plated through hole(PTH) is the crucial process of PCB manufacture. it need be plated enough copper in wall of hole for connect
Most of PCB manufacturers use Al sheet to plug vias.We use blank net to make solder mask and plug vias after many experiences, it's stability and reliability.
As the development of electronics industry, customers put high requirements for PCB surface mounted technology.Via plugging come into being as it connected all circuits,then
HDI PCB is High Density Interconnection PCB, It widely used in small BGA board as its more advantages:
Increased interconnection density by miniaturization of holes,pads and conductors.
Provides the possibility to have a via hole connect direct in the SMD or BGA pad.
Improved signal integrity due to reduced tracklength.
