CO2 Laser Application in PCB Manufacture

Follow electronics technology development,many PCBs outline became more and more complexity. New products on market require PCB outline with high accurate,also appearance is criticized.it’s difficult for traditional outline manufacture. As Laser machining have advantages like high accurate,high speed,low cost.more and more PCB manufacturers start to purchase laser equipment to solve

FPC glue overflow solution

Bubble and overflow glue are common questions of FPC quality.Coverlay flow follow press temperature go up lead to copper pad adhesion glue like epoxy. The reasons of glue overflow It involve many aspects,like coverylay protection in process,FPC factory technology parameter,environment protection,worker operation,etc. One of reasons: Coverlay parameter when making. When CL is coating and

PCB False Weld

If the vias is too close to pad, solder will flow out through via when make reflow soldering,lead to false weld. Countermeasure: Move vias to 0.2mm far away from pad. This kind of question always happened to PCB design. Engineer had to save space for boards limited by dimension. But it may

What is Flex-Rigid PCB Technology?

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

PCB Plated Through Hole-Throwing Power Technology

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

PCB via plugging Technology

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
