support@nextpcb.comHere you'll find insights into PCB design, tech trends, assembly issues, and trending topics
in the general news media as they relate to printed circuit board technology.
As experts in the manufacture and assembly of printed circuit boards, we work to make our blog a helpful resource on PCB topics and the industries that we work with, including automotive, consumer electronics, aerospace and many more.
Recently, I came into contact with a DFM software for PCB boards, which made me a little excited. I wrote an article specifically because I know that it can save me a lot of labor and improve work efficiency in the future.
The so-called electromagnetic interference (EMI) is an electromagnetic phenomenon in which the performance of equipment, transmission channels or systems is reduced due to electromagnetic waves.
We see that FR-4 makes use of epoxy material as a binder. The resin product has a crucial particular criterion: the glass change temperature level Tg, which describes the temperature level shift factor at which a product modifications from a reasonably stiff or "glass" state to a versatile or soft state.
the vias are piercing on the pads on the PCB can be called VIP( Via in Pad). Normally talking, the size of the through in pad must not be larger than 0.5 mm, or else the solder paste will certainly move right into the hole throughout SMT, or the change will certainly stream right into the hole to produce gas throughout home heating, causing inadequate link toughness in between the tool as well as the pad, after that online soldering.
we have compared the wave soldering and reflow soldering, this page is about wave soldering process and its typical process
Thru-Hole Assembly also named through-hole assembly, the modern technology.
HQ Electronics, including HQ NextPCB and HQ Online will be welcoming the auspicious year of the dragon from the 7th of February to the 17th, with the assembly factory closing earlier from the 5th.
To make the designed circuit board achieve the expected purpose, the overall layout of the printed circuit board and the placement of the components play a key role, which directly affects the installation, reliability, ventilation, and heat dissipation of the entire printed circuit board and the direct connection of wiring rate.
For many years, the only way to integrate more functions into a printed circuit board was to increase the board geometry and increase the number of layers.
A motherboard mechanically sustains as well as links digital parts making use of conductive paths. After a circuit board is produced, digital parts need to be attached to it to create a practical circuit setting up.
Hence creating brand-new items constantly require making use of high-frequency substratum, satellite system, mobile telephone getting base station, and so forth, these interaction items need to utilize high-frequency PCB.
EI: Electromagnetic interference, is widely found in various types of electrical and electronic equipment. Various types of electrical and electronic equipment emit electromagnetic waves more or less when they work.
Should be avoided as far as possible in the fine pitch components between the pads through the connection, indeed need to cross the connection between the pads, the use of solder mask to be a reliable cover.
SMD Adhesive is likewise called Surface area Mount Adhesive.SMD Adhesive Features.SMD adhesive must have the complying with Features.
Preface: To ensure a good PCB solderability or electrical properties. Because copper tends to be present in the form of oxides in the air, seriously affecting the solderability and the electrical properties of the PCB, the PCB needs to be surface-finish.
Industrial robots are not only declining in price, but their functions are also increasing. Through the combination of artificial intelligence software, machine vision, and other sensing systems, industrial robots will gain the ability to learn new skills and can further replace humans. work.
RS274D VS RS274X Gerber RS274D Typical Gerber was the very first variation of the PCB documents layout generated by any type of CAD (Computer System Helped Style) system.
Layout considerations
Some experience in reducing noise and electromagnetic interference
It is necessary"to examine MIL-PRF-50884, MIL-PRF-31031, as well as MIL-PRF-55110 criteria to make sure that the PCBs that are being produced autumn in line with the specifications.
