What does IPC mean in electronics industry?
Institute for Printed Circuits
IPC was founded in 1957 as the Institute for Printed Circuits. As more electronics assembly companies became involved with the association, the name was changed to the Institute for Interconnecting and Packaging Electronic Circuits.
What does the dot mean on a PCB?
It is UV cure glue to hold the component during wave soldering. You can see the arrow at the top of the image. Which shows the direction the pcb should go through the wave. Also the IC package has big pads at the end which is also a wave soldering trick. 5.
What is a VIA and what different types are available?
There are three basic kinds of vias: Blind vias: connect an exterior layer to an interior layer. Buried vias: connect two interior layers. Through vias: connect two exterior layers.
How do I know what size PCB to get?
The board size should be larger than the available area. We maintain the tolerance value of ±3mil during the manufacturing. This value is taken into consideration while deciding the board size. Type of enclosure is another factor that we emphasize on while deciding the board size.
What is the IPC 610?
IPC-A-610 is an individual level certification based on a standard published by IPC titled “Acceptability of Electronic Assemblies”. This certification is two-tiered; individuals successfully completing a training course and certification examination. …
What is the black dot on circuit board?
Its actually called Chip On Board or [COB], and the black blob is the protective covering given to the bare bone chip which is the brain of any device that is in.
What is black circle on PCB?
It is an epoxy encapsulation that protects a chip on the PCB board. The abbreviation COB is often used. The bond wires are then connected to the printed circuit board pads using the same automated wire bonders that are used to create ICs. Note the bare tiny leads in the left picture.
What is the purpose of a via?
A via (Latin for path or way) is an electrical connection between copper layers in a printed circuit board. Essentially a small drilled hole that goes through two or more adjacent layers, the hole is plated with copper that forms electrical connection through the insulation that separates the copper layers.
What is stitching via?
Via stitching is a technique used to tie together larger copper areas on different layers, in effect creating a strong vertical connection through the board structure, helping maintain a low impedance and short return loops.
What is the first thing to consider when placing components?
When placing your components, the first thing you should do is make sure they all have enough space. Usually, this means placing edge connectors first, as these may be dictated by the mechanical design. Next, watch out for high pin count components like BGAs.
