Thin core pcb manufacturer with bstpcb.com? With the market demand pushing for thinner devices, people are trying to make the design more portable, lighter, and more flexible, so the application for the extra thin PCB are used more and more widely. Extra thin FR4 PCB can be manufactured as thin as a flexible PCB, bendable similar like a flexible circuit, but more rigid, and cost will be lower, comparing with the same copper traces on each board. For extra thin PCB, we can make it at 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, with or without the solder mask, and copper thickness ½ OZ, 1 OZ, 2 OZ, 3 OZ. See more info at thin core pcb.
Rigid flex printed circuit boards (PCBs) are a combination of rigid and flexible boards. The rigid board is typically made from fiberglass, and the flexible board is generally polyimide. Both are etched with copper before they are bonded together with an adhesive. The finished panel is very strong and can flex without damage. Rigid flex PCBs are for applications where space is limited, and flexibility is required, such as in mobile phones and wearable electronics.
What we provide is not only PCB & MCPCB manufacturing, but also including PCB duplicating, Engineering & process design, components management & sourcing solution, PCB in house assembly & full system integration, surface mounted technology (SMT), full products assembly & testing.
Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.
While Flexible PCBs offer significant advantages, they are also prone to damages. Broadly damages can accrue from two factors: environmental factors and problems that account for issues at the design/fabrication stages. Let us look at both these aspects in some detail. Several environmental factors can cause damage to PCBs, including moisture, static electricity, dust, extreme temperatures, chemical corrosion, and pests. For example, if the PCB is stored in an environment with a lot of moisture, it can destroy the flexible PCB. Moisture can result in a short. Also, given that molds can grow in a damp environment, it will result in a circuit failure. The storage area must be free of any static creating agents. Storing PCBs in carpeted rooms, for example, can result in damage to printed circuit boards on account of the static electricity generated.
According to different manufacturing method, current there’re three basic types for ceramic board: A) Thick Film Ceramic Board Thick Film Ceramic PCB: Using this technology, the thickness of conductor layer exceeds 10 micron, more thick than spurting technology. The conductor is silver or gold palladium, and was printed on ceramic substrate. More for Thick Film Ceramic PCB. B) DCB Ceramic Board DCB (Direct Copper Bonded) technology denotes a special process in which the copper foil and the core (Al2O3 or ALN), on one or both sides, are directly bonded under appropriate high temperature and pressure.

Double sided flex circuits consists with double sided copper conductors and can be connected from both sides. It allows more complicated circuit designs, more components assembled. The major material used are copper foil, polyimide and coverlay. Adhesiveless stack up is popular for better dimensional stability, high temperature, thinner thickness. Dual access flexible circuit board refer to the flex circuit which can be accessed from both top and bottom side but only has only layer of conductor trace. Copper thickness 1OZ and coverlay 1mil, it similar with 1 layer FPC and opposite side FFC. There’re coverlay openings on both sides of flex circuit so that there’re solderable PAD on both top and bottom sides, that is similar with double sided FPC, but dual access flex circuit board has different stack up because of only one copper trace, so no plating process is need to make plated through hole (PTH) to connect between top and bottom side, and trace layout is much more simple. Capability: We are continued to improve our MCPCB, FR4 PCB & FPC & Ceramic PCB manufacturing level to get satisfactory result from customers and ourselves.
A PCB is sort of like a layer cake or lasagna- there are alternating layers of different materials which are laminated together with heat and adhesive such that the result is a single object. The base material, or substrate, is usually fiberglass. Historically, the most common designator for this fiberglass is “FR4”. This solid core gives the PCB its rigidity and thickness. There are also flexible PCBs built on flexible high-temperature plastic (Kapton or the equivalent). You will find many different thickness PCBs; the most common thickness for PCB & MCPCB products is 1.6mm (0.063″). Some of our products- Best Technology boards and Arudino Pro Micro boards- use a 0.8mm thick board.
Heavy Copper Board does not have a set of definition per IPC. According to PCB industry, however, peopel generally use this name to identify a printed circuit board with copper conductors 3 oz/ft2 – 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board. Heavy copper normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors, and so on.
