One of the in-house PCB prototype marvels, Technotronix facilitates PCB prototyping services with no fuss, simple and fast prototyping with a unique way of using advanced techniques like automated layout analysis, algorithms & custom technical specimens depending on the Gerber file and BOM (Bill of Materials) required for a particular prototype.
PCB Prototype is the basic method for making the circuit boards because there are no proper printed circuit boards without designing. Our experience in this genre allows us to build PCB prototypes in just 24 hours.
Technotronix tests the designs deeply to assure the best prototype for the Printed Circuit Board. PCB prototypes get consideration to get the rework if it is needed. For prototyping, our experts use advanced algorithms and techniques. We strongly focus on our client requirements and product quality.
Our quick turn custom prototyping services and inclination fetches quick turnarounds which puts our clients in command of their projects. Adapting a full fledge inspection system and pre- production check to authenticate the prototype quality to make prototypes ready to iterate has been our bonanza.
Technotronix facilitates you for the best prototyping for the proper functioning of your PCB. We assure you to deliver high-quality circuit boards by providing custom prototyping services with the multilayered quick-turn prototype, chips, testing, and others. Our focus is to fulfill every requirement of multichannel industries like defense, IT, medical & many more.
Our flexibility reaches to providing full or partial turnkey as well as consigned PCB assembly with custom prototyping services. To solve the problems pertaining to low volume and highly complex assemblies, we acute Flying Probe Testing. This helps us detect the missing components and validate the component placement. Securing prestige with our clients was possible by offering high tech PCB prototyping services like multi layered quick turn prototype, combined surface mount, chip-on-board (COB) and many other custom prototypes for aerospace, defense, telecommunication, medical and other varied industries.

Benefits of PCB Prototypes
Prototype PCBs are used for testing each component and detect the problems early. Expert engineers can do these. Firstly, engineers check the theories of testing and try to analyze the problem. After that, solve the complexity of the design by testing.
Designing helps to save the extra cost. If any problem is found earlier, then there is no chance of error in the desired product. Prototyping solves the flaws in the design, can adjust the number of materials, and make it better in terms of functionality.
If any issues can be detected during the prototyping, then you can save time. Without doing PCB prototype testing, many problems can occur later. We have implemented few testing methods of any circuit boards, prototype circuit boards to rectifying the errors before final delivery.
Efficient final product
All the problems can be solved earlier by PCB prototypes that result in the desired product. The final product performs efficiently.
Printed Circuit Board Prototypes Classification
There are various stages and methods to test your PCB prototype. Types that are used are classified below:
- Visual models This is the starting step or prototype in the design process. This deals with the overall shape and component structure. This is affordable and easy to design. Physical aspects are the main thing.
- Working This prototype deals with all the functions of the final product. It checks all the features that will work properly or not.
- Proof of concept This prototype checks if the design is valid or not. This checks all the primary factors except the capabilities of the desired product.
- Functional This prototype deals with the final product and gives its overall look and how it will work. Also, identify the materials used so that the cost is low.
PCB Prototypes Process and Technology
Following all the process are necessary for the prototype PCB:
Copper plating and Outer layer imaging
Plating of copper is required by using some chemicals on the surface of the outer layer. In outer layer imaging, you have to apply one more layer of photoresist.
The necessary information should be in a sequenced manner. This will help designers and engineers to produce the products as per the design easily.
List down the bill of materials so that the required products are prepared. The bill of material is based on the quantity, reference designator, value, footprint, and manufacturer part number.
In this step, you need to design the routing. This will help to connect the elements of the PCB.
Creation of photo films
Based on your design, professionals make photo film of the PCB using a plotter printer. A photo film of each layer is required.
Print and align the inner layer
Now, we put copper into the substrate material. Then a layer of photoresist has to be applied. When we apply UV rays, it hardens the photoresist. Remove the unwanted photoresist. Align the layers carefully so that the holes are punched in the right place.
Fuse the layers after aligning. First, you need to layer up the holes. Then, bond it by using a bonding press computer because it controls the heat. Now, remove the extra pins.
Drill the layers to make the holes for the other components that need to be inserted later. X-ray locator helps you to make the hole correctly.
First thing is to design the PCB prototype. There is some software available for the design.
Plating using copper and tin
Again, copper plating is required. The Tin plating protects a copper layer.
Final etching and solder mask
Extra copper is removed by using some chemicals. The required copper is safe by using tin plating.
Apply surface finish and silkscreen
Gold or silver plating is needed for the final finish. Ink-jet writing has the important information that is applied on the circuit board by using silkscreen.
Cutting and Sourcing
Use a router to cut the board from the panel. This is separated after applying the electrical test. Sources of all components are necessary for the PCB assembly prototype stage.
Assembly and Solder paste
All the desired components are attached to your circuit board. Solder paste is used to bond the outer layer of the board.
Pick & place and Reflow soldering
All the surface mount components are placed on the printed circuit board by using a machine. The reflow process is done on both sides.
Inspection and inserting Thru-hole components
Check the quality, poor connections, and electrical shorts. Some PCBs required thru-hole components to send the signals from one side to another.
The final test checks the whole function according to the conditions.
