Blue Circuit Board Electronic Circuit Assembly HDI PCB Sap Bom Transaction
Introduction to PCBs
PCB characteristics: 1. High wiring density, small size and light
weight, which is conducive to the miniaturization of electronic
equipment. 2. Due to the repeatability and consistency of the
graphics, errors in wiring and assembly are reduced, and equipment
maintenance, debugging and inspection time are saved. 3. It is
conducive to mechanized and automated production, improving labor
productivity and reducing the cost of electronic equipment. 4. The
design can be standardized and easy to exchange. HDI PCB is the
abbreviation of Printed Circuit Board, translated into Chinese
called printed circuit board, because it is made by electronic
printing, so it is called "printed" circuit board. HDI PCB is an
important electronic component in the electronics industry, a
support for electronic components, and a carrier for electrical
connection of electronic components. PCB has been widely used in
the manufacture of electronic products. why it is widely used.
Consumer Electronics Industry
Printed circuit boards are bridges that carry electronic components and connect circuits. They are widely used in communication electronics, consumer electronics, computers, automotive electronics, industrial control, medical equipment, national defense and aerospace. missing electronic components.In the current environment of accelerated evolution of cloud technology, 5G network construction, big data, artificial intelligence, sharing economy, Industry 4.0, and the Internet of Things, the PCB industry, as the "mother of electronic products", will become the link in the entire electronics industry chain. base strength.In recent decades, AR, VR, tablet computers, and wearable devices have frequently become hot spots in the consumer electronics industry, making HDI PCB applications widely distributed in the consumer electronics industry, with the characteristics of large demand, large number of orders, and rapid replacement.

FAQ
| Q: What is needed for PCB & PCBA quotation? CESGATE: For PCB: Gerber file and technic requirements(material,size, surface finish treatment, copper thickness,board thickness) and quantity you need. For PCBA: Files mentioned above, BOM, pick and place file. |
| Q: The Wire Bonding process is required when the circuit board is
printed. What should I pay attention to when making the circuit
board? CESGATE: When making circuit boards, the surface treatment options are mostly "nickel palladium gold ENEPIG" or "chemical gold ENIG". If the Al aluminum wire is used, the gold thickness is recommended to be 3μ”～5μ”, but if the Au gold wire is used, the gold thickness should preferably be more than 5μ”. |
| Q: What are the main products of your PCB/PCBA services? CESGATE: Automotive, Military, Aerospace, Industry Control, Medical care, IOT, Smart Home, Robot, Auto parts, Camera, UAV. |
| Q: What are the types of solder mask? CESGATE: There are traditional epoxy resin IR baking type, UV curing type, Liquid Photo Imageable Solder Mask and Dry film solder mask. Currently, the liquid solder mask is the main type. |
| Q: How long is the shelf life of the PCB board and how should it be
stored? CESGATE: 25℃ / 60%RH is recommended when the PCB is stored. The plate itself has no shelf life, but if it exceeds three months, it needs to be baked to remove moisture and stress, and it should be used immediately after baking. It is recommended that the pieces should be loaded within 6 months of storage to reduce the phenomenon of rejection and explosion. |
