No.1 data input stage Whether the information received in the process is complete (including: schematic diagram, *.brd file, bill of materials, PCB design specification, PCB design or change requirements, standardization requirements specification, process design specification and other documents). Make sure the PCB template is up to date. Whether the clock layout is reasonable. Confirm that […]

When PCB is to be processed by SMT, PCB is transported by guide rail on SMT production line. Therefore, a pair of edges of forbidden cloth elements must be reserved as transport edges. Usually, the two long sides of the PCB or the rear panel of the jigsaw puzzle are used as its conveying edges. […]

With the pitch of ball grid array package (BGA) decreasing from 1.0mm to 0.8mm, 0.4mm or even smaller, the technological development of component packaging industry is obvious. At the same time, it becomes more and more difficult to fan out and route the dense circuits related to these components. At present, high-density interconnect (HDI) method […]

1.PCB VS flexible printed circuit board PCB is one of the important electronic components in the electronic industry. Almost every kind of electronic equipment, such as electronic watches, calculators, computers, communication electronic equipment, military weapon systems, etc., as long as there are electronic components such as integrated circuits, all need to use printed boards for […]

In electronic design, PCB is the physical carrier of our design content, and the final realization of all our design intentions is represented by PCB. Such PCB design is an indispensable link in any project. However, in the previous design, due to the low frequency, low density and large distance between devices, PCB design was […]

The key to realize high-precision deep milling of PCB is that the grating ruler on each axis can sense the board surface, so that the descending depth of each Z axis can be controlled separately, and the axes can work independently in coordination to realize mass production processing. Here, the main influencing factors are analyzed: […]

PCB process failure: debris appears on the hole wall. Reason: (1) the material of cover plate or base plate is inappropriate. (2) The cover plate causes the bit damage. (3) The vacuum pressure of the spring central head of the fixed drill bit is insufficient. (4) The pressure foot gas supply pipeline is blocked. (5) […]

What you must know about ESD as a PCB LAYOUT engineer. TVS tube is widely used in practical PCB design. Silicon transient voltage absorption diode has extremely fast response time (sub-nanosecond level), quite high surge absorption capacity, and many voltage grades. It can be used to protect equipment or circuits from static electricity, transient voltage […]

Numerical control device is the core of the whole numerical control system, and its hardware structure can be divided into big plate structure and functional module structure according to the plug-in mode of PCB in CNC device. (1) CNC device with large plate structure can be composed of main circuit board, position control board, PLC […]

The purpose of this test is to verify the resistance to electrostatic discharge (ESD) caused by the approach or contact of objects or people or devices. Or people’s interior can accumulate electrostatic charges higher than 15kv voltage. Experience shows that many unexplained failures and damages are probably caused by ESD. Through discharging from the ESD […]
