How to distinguish HDI circuit board is several levels of blind buried?

The trend of printed boards in global shopping malls is to introduce blind buried hole circuit boards in high-density interconnected products, and then more useful space saving, so that the line width, line spacing is thinner and narrower.

Frequently asked Questions about purchasing circuit boards

In production, we will have the engineering review and approval of your information, if there is a problem the first time to combine with you! In order not to delay your time, the combination form you provide must be accurate.

What materials and classification do pcb circuit boards have?

Copper clad plate is the basic material of electronic industry, mainly used in the processing and manufacturing of printed circuit board (PCB), widely used in TV, radio, computer, computer, mobile phone, communication and other electronic products.

Introduction to reliability test of PCB circuit board

PCB circuit boards play an important role in life today. It is the foundation of electronic components and the highway. In this regard, the quality of the PCB is critical.To check the quality of a PCB, a number of reliability tests must be performed. The

Common circuit board and multilayer PCB circuit board difference pcb

With the reduction of the aperture, the original debris that has no effect on the larger aperture, pcb board factory, such as brush debris, volcanic ash, once remaining in the hole, will make the chemical precipitation of copper, copper plating will lose

Copper clad PCB circuit board solution

Even the well-written and actually implemented technical specifications for PCB laminates do not specify the test items that must be carried out to determine that PCB laminates are the cause of manufacturing process problems.

What are all kinds of strip holes and round empty pads on the circuit board?

The holes on the circuit board are divided into overcurrent holes, plug-in holes and installation holes.

High density printed circuit boards for DC converters

The PCB layout determines the performance of a switched power converter. You don't have to spend countless hours debugging EMI, noise, signal integrity, and other issues associated with poor layout.

Influence of loss performance on high speed circuit boards

In addition to the machining technology, back drilling design and stump control also have some effects on PCB loss.

What are the common problems of PCB circuit boards? It is good to know these for your PCB design

Poor insulation of copper wire will lead to arc between copper wire and copper wire. Too close between the copper trace and the path, it is easy to short-circuit risk; The lack of thickness of the circuit board can lead to bending and breaking.

PCB circuit board processing using which ink?

After the circuit is completed, solder resistance ink is coated on the circuit as protection of the circuit. There are liquid photosensitive, heat curing and UV hardening.

The production method of the key process of embedded copper printed circuit board

Embedded copper printed circuit board has the characteristics of high thermal conductivity, high heat dissipation and saving board space, which can effectively solve the heat dissipation problem of high-power electronic components.
