Vishal International : 40 Year Of PCB Fabrication in India

Vishal International : 40 Year Of PCB Fabrication in India

There are many competent players in the Indian market who are skilled and are delivering quality products through online platforms and instant quote facilities, attracting many beginners to engage. One such manufacturer is Vishal International about whom we will be discussing in detail today.

About the Manufacturer:

Established in 1980 Vishal International has more than 40 years of experience in the field of PCB manufacturing. They are based in Bangalore, India and today they deliver products not only in India but also in the U.S.A., Israel and Canada. Experience of decades has given them edge and they have sprawled into multiple PCB related capabilities and have attracted customers from both private and public spheres. 

They provide PCB Assembly for small, medium & bulk quantities with high precision and accuracy.

Key Highlights:

The various highlights that set Vishal International apart are:

  • Instant Quote and Price Calculator: Using their platform, mentioning the order details you can directly know the cost that will be incurred in the process without any ambiguity. 
  • Free Delivery and No Setup Charges: Not only you can order just one PCB, it will be delivered to you in India without any additional charges, thus making the deal very cost effective.
  • Blazing Fast Turnaround Time: The fabrication claims to deliver 1-2 layered PCB in less than 24 hours and multiple layered PCB within 48 hours of order placement.
  • Array of PCB Layer Options: Unlike other manufacturers who provide maximum upto 4 or 6 layers services, Vishal International provides upto 8 layers along with Al Metal Core option available as well. 
  • Advanced PCB Services: Not just FR4 based PCB services are available here but also advanced PCB services like RT Duroid, blind buried vias, etc are also available. 
  • High Customization: Panelization, board outlines, solder mask, legend, clearances and the list goes on for the PCB specifications that they provide thus making the PCB highly customizable as per your requirements. 

Array of Customers:

Having years of experience and gaining ground over the years their client base is quite impressive. They supply PCB to an array of industrial segments like electronic, electrical, telecommunications, defence, home appliances, automobile, aerospace medical, power sectors, manufacturing, LED lighting and many other fields. Their customer base is not limited only in India but also posted in varied geographical areas. 

Capabilities Compass:

FR-4 PCB Services:

Naked proto is mostly used by students is both cost effective and quick delivery time. Other options available are single sided PCB, double sided PCB, multi-layer PCB and metal clad PCB:

  • Naked Proto- This board is without solder mask and silk-screening. It is made with FR-4 glass epoxy grade material and can be processed for 1 – 4 layers.

  • Single Sided PCB- Lower cost, especially for high volume orders they are popular and easily understood by most PCB manufacturers. A thin layer of thermally conductive but electrically insulating di-electric is laminated with copper. Solder mask is usually applied on top of the copper. Useful for calculators, surveillance, LED lighting, coffee makers, etc.

  • Double Sided PCB- They are gateway to higher technology applications. Mostly used in converters, power monitors, traffic systems, etc.

  • Multilayer PCB- Unlike a Double-Sided PCB which only has two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material which are buried in the center of the material. Used in computer systems, GPS technology, satellites, etc.

  • Metal Clad PCB- Used mainly for heat management of assembled PCB. Mostly Al or Cu is used as base substrate that dissipates heat quickly. Mostly used in LED lighting and power conversion systems.

Advanced PCB Services:

Blind buried vias, RT duroid, multi-layer RT duroid and control impedance is available. 

  • RT duroid– They are PTFE composites reinforced with glass microfibers that result in exceptional dielectric constant uniformity and these are used in commercial airline broadband antennas, micro strip and strip line circuits, etc.

  • Buried and Blind Vias- Blind & Buried Via technology has played a pivotal role in squeezing more capability into a smaller space.

  • Control Impedance- A controlled impedance PCB is a circuit board which is manufactured to achieve specified impedance (ohms) on specific track features relative to a particular ground-plane. They are used in fast digital applications like telecommunication, RF communication, signal processing, etc.

Special Specification and Stencils:

For highly customized PCB to suit the requirements of their customers, Vishal International has provided a separate order window catering special specifications.

How to Place an Order?

To place an order you will have to register to their platform first. Once registered, on login your dashboard will look like this:

Based on your requirement you can select the desired option and place order.

Lead Time and Value for Money: 

Various lead times based on working days (WD) and the total cost incurred is shown for different combinations of specifications and quantities.

For the same PCB quantity the total cost incurred differs, for quick delivery in three days the cost is just double than delivery in 10 days. Some of the features mentioned like 1 working day and single sided layers do not work. Further, in some cases the 6 layer option works and in some it does not. 

The special specification PCB cost calculation works only when you upload Gerber file:

Even after uploading the Gerber file, the calculation does not happen instantly, so for special specification the ‘instant quote’ feature is redundant. The same is true for stencil order too, you can’t access the PCB calculator instantly.

Other Important Details:

Payment and Refund:

Once the order is placed and you upload the Gerber file, you can make payment to complete the placing order process. The details of mode of payments accepted by them are not available on their platform.  Further, once the order is placed, it cannot be cancelled. In case of cancellation by the customer, refund is not available. However, if the cancellation happens from their end, the money will be refunded.

In case of quality issues on the delivered product or non-alignment with the Gerber file or specifications mentioned by you, the product will be replaced and delivered afresh without any extra cost incurred.

Delivery Services:

On placing the order after 12 PM, the delivery time is counted from the next date to calculate the lead time. Further, time determined is mentioned only for the manufacturing process and dispatch transit time is not included. The mode of delivery used by them is not available on their platform. 


Why you should choose Vishal International:

  • Instant quote and quick delivery is available along with real time PCB price calculation for comparison.
  • Highly customized PCB can be ordered using their platform, very suitable for professionals.
  • Upto 8 layer PCB board can be made along with other options like Al metal core.
  • Advanced PCB services are available. These services are required by high end industries like aerospace, defence, etc.

Why you shouldn’t choose Vishal International:

  • PCB assembly and component sourcing services are not available on their dashboard. 
  • Details about payment, delivery and quality assurances are not clearly stated on their platform unlike other online top manufacturers.
  • Customer service is not prompt and you will have to wait for them to respond for days.
  • Without registering you cannot compare prices and in case of stencils and special specifications without a gerber file no price details are available so the whole concept of ‘instant quote’ is negated. 
  • Suits more professional customers rather than individuals like hobbyists, etc.

Taking into consideration the above mentioned information and detailed analysis you can make an informed choice about choosing a manufacturer for your PCB requirements.
