This is very interesting . Who knew this existed ? I wish AL PCB's were easy available for DIY.
I made a LED light with 80 white LED's , and ran into dissipation problems .
The one sided AL pcb would solve that .

Led applications are one of the biggest users of aluminum pcb
Yes, aluminum material not only has good thermal conductivity, but also has low cost. Many of our customers in the LED industry will come to us to produce a batch of 1-layer aluminum plates for them.

How much for a standard 100x100 board?
I want to compare prices but not willing to sign up and submit gerbers for a quote.
Thanks.

Aluminum PCBs are quite common, actually. If you have someone do the assembly for you, make sure they can work with it. Aluminum tends to suck up a lot of heat which can be a problem during reflow.

PCB Assembly
Yes I agree with you, actually we are also a one-stop service provider, if you prepared BOM list, we can purchase components for you in a cheaper price, reason you can see this:
PCBONLINE - Circuit Board Component Sourcing for Advanced Circuits, EMS Service Provider
we also will test all the PCB assemble for our customer,
Unlike other PCB assembler whose AOI is only 2D-scanning, we use 3D-scanning. Any possible defects are noted on the screen, and our AOI operator checks them one by one and records if there are any real defects. The defective products will be picked out. Then another technician checks the PCBAs visually, and the samely, any defects will be recorded, and defective products will be picked out. Next, some PCBA samples will go through the sampling inspection in the testing area. All the defective products will be sent to be repaired, and after repairing, they are also separated from other PCBAs.

Is this the price even for 1 100x100mm PCB, or are there any minimum order limit?
hi, we don't have a minimum order quantity for our customers.
We can serve a wide range of customers, including traders specializing in LED, university students and circuit design researchers. Generally, their orders are not large, including 1 pcs, 2pcs, 5pcs and so on🙂.

I've been looking on your website , but cannot seem to find the exact material that is used for the dielectric layer .
Only this : The ceramic filler is adopted in the insulation layer of all double-sided aluminum substrate to ensure thermal conductivity and plate non-layering and avoid other undesirable issues.
What material is the insulation/dielectric layer?
Do you have outlets in south east Asian coutries to buy bare AL PCB's ?

As do many others. My assembly house inspects the deposited solder paste with a 2.5D AOI, the part placement (before reflow) with 2D AOI, and the finished PCBA with 3D AOI.

PCB Material

Yes I've seen that .
PCBs’ performance, quality, manufacturing cost, and manufacturing level all depend on CCL (copper clad laminates). CCL can be divided into a rigid type and flexible type according to the used PCB materials. Rigid CCL is made of reinforced material, impregnated with resin adhesive, dried, cut, and laminated, then covered with copper foil and steel plate, and formed in a hot pressing machine at high temperature and high pressure. While flexible CCL is composed of copper foil, an insulating film, and an interlayer adhesive, which are compounded and processed by hot pressing. Below we use CCL to let you understand PCB materials clearly.

because you cannot see that, so I try to paste it in here for you.
PCB Materials for Rigid CCL：
Rigid CCL is made of copper foil and PP.
Copper foil is an indispensable raw material for CCL production. It is divided into RA (rolled annealed) copper and ED (electrodeposited) copper.
• RA copper foil is made by rolling a copper plate repeatedly. It is mainly used for FPC CCL.
• ED copper foil is a primary product produced by a special electrolytic machine and then processed by the finishing process. According to the thickness, its specifications can be divided into 9um, 12um, 18um, 35um, and 70um.v
PP means that fibers are woven, and resin (epoxy resin or phenolic resin) is used to bond them together in the manufacturing process. To decide which type of PP meeting for your requirements, you can consider its quality characteristics of resin content, resin flow, gel time, and volatile content. Its different types are:
• Woven glass fabric: it is made of glass fiber, and its composition is Aluminum borosilicate, which has high insulation performance. It has the advantages of a large breaking strength coefficient, good dimensional stability, not easy deformation, and uniform weight and thickness.
• Glass fabric paper: also known as glass fiber non-woven fabric, it is one of the main raw materials of CEM-3. It uses E-type glass fiber with a diameter of 5-10um chopped by a paper-making process and dispersed in an aqueous solution. After eliminating lumps, it is made into a uniform paper product on a short mesh paper machine. This kind of PCB material’s price is much lower than that of glass cloth.
• Impregnated fiber paper is a material composed of pulp components
• Resin: it includes Phenolic resin and epoxy resin.
2. PCB Materials to reinforce PCB
The PCB materials below are used for a dielectric layer to reinforce the PCB.
1. Phenolic material：it is used for a dielectric layer that uses phenolic resin as adhesive and wood pulp fiber paper as reinforcing material. Its specifications include FR-1, FR-2, XPC, and XXX PC. It can be punched, and it has the advantages of low price and small specific gravity.
2. Epoxy material: it is used for a dielectric layer that uses epoxy resin as adhesive and glass fiber cloth as reinforcing material. Its specifications include FR-4 and FR-5. This kind of PCB material has high dimensional stability and impact/moisture resistance, and it is used most.
3.Composite epoxy material: it is used for a dielectric layer that uses epoxy resin as adhesive, wood pulp fiber paper as the reinforcing material’s inner core, and glass fiber cloth" as reinforcing material’s surface. Its specifications include CEM-1 and CEM-3. Its performance is between phenolic material and epoxy material.
4. Metal material: It consists of a metal layer, dielectric layer, and copper foil. Its specifications include aluminum base and copper base. It features good heat dissipation.
5.Ceramic material: this kind of PCB material includes AL2O3, AIN, and SiC.
6. Other material: other material is used for a dielectric layer that uses other special resin as adhesive and glass fiber cloth as reinforcing material. Its specifications include PI (Polyimide), PTFE (Teflon), and BT. It has the advantages of high TG, low water absorption, low dielectric constant, and low dielectric loss.
According to rigid CCL’s flame-retardant characteristics, PCB materials can be divided into UL94-V0 and UL94-HB.
According to rigid CCL’s performance, PCB materials and boards themselves can be divided into the high-frequency, high-TG, and low-CTE.
3. PCB Materials for Flexible CCL
Flexible CCL is made of copper foil, an insulating film, and inter-layer adhesive.
Flexible CCL’s insulating film can be divided into two types, namely the polyester film and polyimide film.
• Polyester film’s thickness is 25um-125um. It has good dielectric performance, good chemical resistance, and low hygroscopicity, but it’s not good as polyimide film in heat resistance and dimensional stability.
• Polymide film’s thickness is 7.5um-75um. It has good dimensional stability and thermal stability and can be used continuously at working conditions under 200°C.
Flexible CCL’s inter-layer adhesive is used for the adhesion between the copper foil and the insulating film. Its materials include epoxy resin and acrylic resin.
• Epoxy resin has high heat resistance, good dielectric performance, and good chemical resistance.
• Acrylic resin has better processability and excellent flexibility.
According to used PCB materials of the boards, you can custom buy rigid PCB, rigid-flex PCB, flexible PCB, high-frequency PCB, high-TG PCB, halogen-free PCB, lead-free PCB, aluminum PCB, thick-copper PCB, ceramic PCB, carbon ink PCB, carbon nanotube PCB from PCBONLINE.

I have answered other questions for you, and about your last question, we sell bare AL PCB, we are a factory connected online shop.
Anyone taking apart floppy drives, as those had this as the PCB under the drive motor.
