PCB circuit

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.

How does PCB circuit board copper-clad laminate do?

Once a PCB laminate problem is encountered, it should be considered to add to the PCB laminate material specification.

PCB circuit board inner plug hole process

In the era of HDI high-density connection technology, the line width and line distance will inevitably become smaller and denser, and thus a different type of PCB structure is derived.

Technical development of PCB circuit board

Mobile terminal with HDI board is the main point of PCB growth. The mobile terminal represented by smart phone drives HDI board higher density and thinner. PCB all to high density fine line development, HDI board is particularly prominent.

The difference of holes in PCB circuit board processing

Through the hole plug oil process is one of the hole treatment methods, the first is to opaque, above must have ink cover, plugging; The second is the hole can not appear yellow phenomenon, and do not touch tin.

The cause of PCB circuit board bubbles have those?

Board bubbling is one of the most common quality defects in PCB production. Because of the complexity of PCB production process and process maintenance, especially in chemical wet treatment, it is difficult to prevent board bubbling defects.

Cause of copper cable loss of PCB circuit board

The abnormal quality of PCB board will cause direct losses to customers and PCB manufacturers. The loss of copper wire is one of the abnormal quality phenomena, but this kind of abnormal will cause greater losses to PCB manufacturers.

Current development trend of PCB circuit boards

The PCB industry has been shifting its focus to Asia, gradually forming a new pattern with Asia as the center and other regions as the auxiliary. The Asian continent has become the main production base of PCB and its high-end products HDI in the world.

Heat dissipation of the PCB circuit board

For electronic equipment, a certain amount of heat will be generated when working. If the heat is not dissipated in time, the equipment will continue to heat up, and the devices will fail due to overheating.

How to distinguish PCB circuit board welding

Because some standard thickness of the circuit board is not the same size, so the customer can measure some checks, according to their own product thickness and specifications, and then the light and color, in the external circuit board and ink cover, fol

Circuit board ROHS test, pcb circuit board ROHS test cost

The Circuit Board can be called Printed Circuit board or Printed circuit board, the English name is (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board.
