Rigid Flex Main PCBA Soldering Layout Surface Mount Resistor Smd Machines
Main PCBA Application - Multilayer Board
Multi-layer board: The required circuits are made on the front and
back surfaces of multiple double-sided boards, and an insulating
layer (Prepreg) is sandwiched between the two double-sided boards
and then pressed together to form several layers of copper. The
construction of the wire is usually an even number of layers due to
the use of multiple double-sided laminates. The number of copper
wires that can be made by multi-layer boards is the largest, and it
is used in more complex circuits. At present, the motherboards used
in computers mostly use eight-layer boards because of too many
components. Generally, small electronic products, such as mobile
phones, tablet computers, etc. Due to the requirement of small
size, at least an eight-layer board is required. The more
electronic components, the smaller the product size, and usually
more layers of Main PCBA are required.
1. Material
FR-4 (glass fiber epoxy resin substrate) is the most widely used
material in the global electronics industry. FR is a code name for
a flame-resistant material grade, which means a material
specification that the resin material must be able to
self-extinguish after burning. It is not a material name, but a
material grade, so there are many types of FR-4 grade materials
currently used in general circuit boards, but most of them are
four-functional epoxy resin plus filler (Filler) and glass fiber.
The composite material made. In recent years, due to the
development of electronic product installation technology and Main
PCBA technology, FR-4 products with high Tg have appeared again. Tg
degree (glass transition temperature - Glass Transition
Temperature)
Example: ISOLA FR402, FR408, 370HR South Asia NP-140, NP-155, NP-175

FAQ
| Q: Can your company provide the serial number when making circuit
board text? CESGATE: Serial numbers can be provided, and in addition to text serial numbers, QR-CODE can also be provided for customers to query. |
| Q: The lead-free process is required when the circuit board is
printed. What should I pay attention to when making the circuit
board? CESGATE: The lead-free process during printing is higher than the temperature resistance requirements of the general process, and the temperature resistance requirements must be above 260 °C. Therefore, it is recommended to use a substrate above TG150 when selecting the substrate material. |
| Q: What is your delivery date? CESGATE: The general sample delivery time is 6 working days for single and double-sided boards, 7 working days for 4-layer boards, and an additional working day for every 2 layers. However, if there are special processes, additional working days will be added according to the situation. Generally, the delivery time for mass production is 10 working days for single and double-sided panels, and 15 working days for multi-layer panels. However, if there is a special process or more than a certain number of working days, the working days will be additionally increased according to the situation; you can also pay the urgent fee to shorten the number of days, please contact Contact the business specially proposed, depending on the individual situation to provide expedited days. |
| Q: Why choose us? CESGATE: Professional and experienced R&D team. Advanced production equipment, scientific and reasonable process flow. Reliable and strict quality control system. We test all our products before shipment to make sure everything is in perfect condition. |
