- Tec-speed 20.0
This material is capable of offering unparalleled frequency performance with the highest level of dependability and the best loss characteristics available.
A Ventec PCB constructed of this kind of PCB material is designed for the most demanding applications that require a high frequency.
It is possible to use Ventec PCB, polyimide, or epoxy-based materials with VT-5A2 since it offers a polymer matrix that is completely compatible.
As a result, it is an excellent choice for you if you are looking to produce multilayer Ventec PCBs that have a lower loss ratio.
It offers the highest thermal conductivity performance, the highest glass transition temperature, as well as the finest thermal performance possible.
When it comes to excellent heat management for an insulated metal substrate that is intended for forming and bending according to the application, VT-4B is the most reliable choice as it has the appropriate characteristics and performance required.
Its minimal radius makes it simple to be installed in confined locations, which is ideal for standard PCB assembly.

What is the Desmearing Process Employed for in Ventec PCB Fabrication?
The desmearing process involves removing drilling debris and leftover resin which has been melted due to the abrasion from drill holes on a Ventec PCB.
This process is carried out by treating the circuit board with plasma or permanganate.
Heat is generated during the procedure of drilling holes in the circuit board, which causes the epoxy resin to spread across the connections of the inner layer.
The epoxy spread on the surface must be wiped away before any further plating can be done.
You may also avoid the desmearing process by employing some techniques, such as micro roughening, which helps to enhance the adherence of resin coatings on the Ventec PCB.
Desmearing process in ventec PCB
What is the Estimated Thickness of a Ventec PCB?
Depending on the kind and quantity of prepreg plies or layers that are used in the laminate employed by a Ventec PCB, you can determine its thickness.
A particular thickness is present in every fabric type when it is treated with resin and given a certain weight.
The thickness may be determined theoretically based on the density and weight of the resin, as well as the density and weight of the cloth.
In addition, it is essential to remember that the weight of the laminate may vary by as much as 5% from one roll to another.
To ensure the entire laminate thickness, it is preferable to monitor the total final weight instead of simply measuring resin content, since this is a more precise method.
You may have a sole fabric with many different finishing weights, which, when plied, will result in a different final laminate thickness for the completed laminate.
The thickness range that you should opt for in your Ventec PCB should be around 002” to .200” and with copper foil weights ranging from 1/4oz to 12oz.

Ventec PCB used in satellites for broadcasting
What is Meant by the TD Value of Ventec PCB?
TD stands for Thermal Decomposition and refers to the decomposition caused by heat in a Ventec PCB.
The chemical properties of the materials in a Ventec PCB have a considerable impact on their temperature.
The temperature ranges from around 300 degrees Celsius which is mostly found in epoxy systems to more than 400 degrees Celsius for certain polyamides and polyurethanes.
When a PCB material reaches a temperature at which it begins to thermally degrade, it is referred to as its TD temperature.
It is also referred to as the temperature at which a laminate has decomposed to the point that it has lost 5 percent of its original weight as a result of decomposition.
Because it is at this temperature that significant weight loss begins to occur, the onset temperature of the laminate would provide a more accurate performance measure.
By the time a PCB material has shed five percent of its original weight through decomposition, it may be rendered unsuitable in the majority of applications.
Can You Employ the Usage of Resins in a Ventec PCB?
The resin content of a PCB prepreg refers to the percentage of the total weight of the PCB prepreg that is made up of resin.
In order to determine the amount of resin present in fiberglass reinforced laminates and prepregs, the usual test technique is to burn them out.
A loss of weight due to burnout is carried at 1100 degrees Celsius, after which the final weight is deducted from the starting weight.
The resin content is referred to as the difference between the initial and the final weights, which is often expressed as a percentage.
When organic reinforcements are employed in Ventec PCBs, a “basis weight” method is utilized to determine the resin content of the boards.
Using this technique, the initial weight of the laminates may be determined, with the assumption that the weight is consistent across the laminate roll.
The resin content is then determined by subtracting the base weight from the coated weight and multiplying the result by the number of grams of resin in the coating.
When a PCB laminate is pressed, the thickness of the laminate is determined by the flow and resin content.
They also calculate the quantity of resin that will be required to fill the copper layer inside of the structure.
The amount of Ventec PCB resin on a board has a significant impact on a variety of characteristics such as the dielectric constant, drilling and etching quality, dimensional stability, and coefficient of thermal expansion.
What are the Factors that You Need to Consider for the Construction of Your Ventec PCB?
During the Ventec PCB manufacturing process, there are five different areas that must necessarily be considered, each of which is particularly connected with the selection of prepregs and laminates.
However, particular recommendations for low-flow, epoxies, polyimide, and filled systems may vary from those for other Ventec PCB materials.
The following are the critical components that must essentially be kept in mind during the manufacturing of Ventec PCBs:
Preserving the dryness of the treated inner layers and prepreg prior to lamination.
Temperature control inside the laminating press is essential to ensuring consistent melt flow throughout the press chamber.
Assuring that the lamination temperature is appropriate for the PCB material being used is essential.
Guaranteeing that the cure period is long enough to achieve the glass transition temperature is also critical.
Cooling down in a controlled manner to prevent warpage should be adopted.
What are the Different Procedures to Measure Prepreg Flow in a Ventec PCB?
There are a number of distinct methods for measuring prepreg flow in a Ventec PCB, each of which represents a different approach to the flow:
Flow test using a standard 4-ply:
Reducing prepreg pieces to a certain size and weighing them before compressing them under controlled pressure and temperature are the steps involved in this flow testing technique.
Afterward, a tiny piece of the resin is cut out of the center and weighed again before being adjusted back to the original region of the resin flow.
It is the weight loss that occurs between the initial PCB material and the final obtained “flow biscuit” that is measured as the flow which is denoted by a percentage.
In cases when it is feasible, standardization of the technique is highly encouraged.
Increasing the number of plies results in higher flow values.
Creating a standardized Ventec PCB prepreg is difficult due to the fact that various users may have varying demands from the same material.
The Scaled Flow (SC) test:
In order to reap the full benefits of this procedure, you should include both Delta-H and scaled flow in the same analysis.
Taking the two factors into consideration would provide an excellent estimate regarding the overall thickness of the final ply produced by the prepreg process.
In addition, this test also provides information on the flow amount that occurred in order to accomplish the desired outcomes.
Low-flow (NF) assessment:
The low-flow test involves measuring the amount of resin that flows through holes with a diameter of one inch or less.
This diameter indicates the size of the cutting area of a Ventec PCB.
This method is used to determine the flow of materials that are designed for applications that necessitate the use of rigid-flex and heat sink bonding.
NF assessment is the most suitable in situations where the prepreg is required to bond layers of material together.
However, it is not acceptable to allow extra prepreg to flow into cut-out portions or into areas where the flex material needs to move freely in order to maintain structural integrity.
Rheological characteristics measurement:
The rheological characteristics can be evaluated using a variety of equipment that is capable of measuring the viscosity of the resin system either when it is melted or even during the melting process.
The Oscillating Disc Rheometry (ODR) test is a complicated procedure that provides information on the change in heat-up rate, temperature, and rheology over time.
The rheology data gives an indication of the type of material flow during processing.
What do You Understand by the Traceability of a Ventec PCB?
If anything goes wrong in your PCB, the source of the problem may be tracked down and the boards that need to be examined or changed can be identified through the traceability process.
This process ensures complete tracking of your Ventec PCB, its components, and operators.
Traceability is accomplished via the use of a serial number printed on each reel.
It is necessary to have access to related information, such as the supplier, lot number, and quantity of components.
During the course of production, all important data, such as the amount of time spent on each machine, the number of operators engaged, and the components used, is updated in the database for each PCB.
How can You Maintain Prepreg Flow in a Ventec PCB?
Typically, a process adjustment is required to ensure proper prepreg flow for a particular Ventec PCB design, such as:
Changing the laminate pressure:
A moderate change in pressure will result in a little increase in the flow, which may be sufficient to allow you to establish the proper environment for your Ventec PCB.
Changing the rate at which the press heats up:
This action requires a greater amount of adjustment than simply changing pressure and should only be used if pressure alone is not sufficient to correct the process.
If resins are heated more gradually, they are more likely to show decreased melt viscosities and a much slower flow.
Reducing the prepreg flow:
When utilizing a low-flow prepreg, you may need to considerably reduce the amount of prepreg used in order to prevent it from leaking out of the flow bead and into the cutout region.
It is usually possible to fix a small flow issue by modifying the cutback without having to change the process.
You may make the adjustment for a single or two unique cuts that are overflowing heavily without affecting the others, or you can make the modification for the whole lamination process.
Changing the temperature or pressure rate of the circuit board has an equivalent impact on the whole Venture PCB.
What is the Certificate of Compliance for a Ventec PCB?
Certifications of compliance are necessary for every consumer to obtain and every manufacturer to provide as they prove that the products have been tested by authorized organizations and are safe to use.
Some of the prominent certifications that should be followed strictly include the following:
- Military (MIL-PRF-31032) certifications
- AS9100 Certification
- International Traffic in Arms Regulations (ITAR) Certification
- IPC Certification
- Printed Board Process Capability and Relative Reliability (PCQR 2) Certifications
Moreover, PCBMay also possesses certain additional certificates of compliance that make them unique and elevate its status in the industry.
These certificates include ISO 9001:2008, ISO 14001:2015, UL certification, Restriction of Hazardous Substances Directive (RoHS) certification, and Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) certification.
What are the Electrical Properties of Ventec PCB?
A Ventec PCB possesses the following electrical properties and you should also ensure that the Ventec PCB that you are purchasing is also equipped with these electrical characteristics:
Its dissipation factor is quite low. You should check the dissipation factor of your Ventec PCB as it assists in increasing the amount of power supplied and also permits high-power PCB applications.
Rapid signal transmission is made possible by a low dielectric constant (Dk) which is prominent in a Ventec PCB.
Both the dielectric constant as well as the dissipation factor of the Ventec PCB are consistent and should continue to be so, as this avoids phase distortion and provides uniform transmission line impedance across the entire operating spectrum.
What is the Procedure for Copper Treatment in a Ventec PCB?
Copper surface treatment for ventec PCB
For the treatment of copper in Ventec PCBs, the typical technique involves depositing tiny copper nodules all across the copper “teeth” present on the foil bath-side of the circuit board.
You may choose to even plate nickel, brass, or zinc over the deposited copper nodules in order to reduce oxidation while also improving thermal stability.
Another option is to apply an alternative treatment consisting of an extremely thin layer of zinc chromate or an additional antioxidation treatment to enhance the results.
This aids in the prevention of oxidation around the even edge of the foil or the drum’s surface.
Copper adhesion is achieved via the use of a combination of chemical and physical bonding.
Copper foil that has been electrodeposited has a natural “tooth design” that was formed during the electro-deposition process.
The nodular copper treatment provides a locking mechanism if the resin plates are used in conjunction with the copper teeth and help to preserve the copper teeth.
Chemical treatment of copper foil may also help to strengthen bonding.
The majority of foils now in use include proprietary silane or other treatments that chemically enhance the connection between the foil and a variety of different resins.
