Prototype PCB Assembly

Turnkey PCB assembly is one of our specialties. With our skilled engineers, soldering specialists SMT Process Engineers, and Component Procurement experts, we offer an affordable and extremely versatile assembly process for PCBs that comes with rapid turnaround.

We provide the complete PCB assembly for prototypes ranging from 1 up to 20 boards. This service lets you develop complex designs for testing using high-end professional electronic assembly craftsmanship and you don’t need to be concerned about the quality of assembly affecting the results of your tests. We have designed our prototype assembly area with a unique layout that allows for a flexible combination of automated and manual part loading. We also have the ability to handle fine pitches components and BGAs for high-density boards like FR-4.

Turn-Key PCB Assembly is our primary business, and we even provide prototype projects. With our knowledge and experience, We can complete everything for you, from PCB prototyping as well as component purchase as well as circuit board assembly, all the same under one roof. We also can assemble using kits as well as Consigned parts If you would prefer.

Do not stress about sourcing components for PCBs and concentrate more on the your design! To ensure a smooth procurement process, our procurement team will work with as many component distributors as necessary.

To decrease total costs, we will optimize packaging (cut tape, tube, bulk, etc.) and versus quantity smaller Bills of Materials (BOMs). We have the ability cross-reference parts, including difficult-to-find and out-of-date items. Your BOM is a guideline to which part numbers and manufacturers we will purchase, so you won’t have to worry about part quality issues caused by unauthorized substitutions

The total cost for Turn-Key is the sum of labour costs for the PCB Assembly costs, the bare PCB Manufacturing cost and component cost.

We will use Digi-Key Electronics, Mouser, Avnet, Arrow, Future, Newark or another distributor to determine component prices. We never mark-up any component costs or any handling charges.

We are aware that on-time delivery is crucial, which is why we have designed the turnkey process to make it as effective as it can be. As soon as the parts procurement process is completed, PCB manufacturing begins. We carry out an extensive DFM check and discuss engineering issues and Component issues with you prior to when the assembly process begins. Turn-key Circuit Card Assembly generally takes about 2 weeks, less if there aren’t any difficult-to-find components or errors in the documentation.

We at JarnisTech place a high value on customer satisfaction and quality, which has helped us build a long list of satisfied clients. If you’d like to work with a supplier of PCB assemblies for prototypes in China, do not hesitate to call us at 0086-0075-23034656 or contact us with your inquiries or needs via [email protected]. Our specialists will help you throughout the various steps of the initial PCB construction process. We are looking eagerly to making your time with us even better as well as more enjoyable.

PCB Prototype Assembly Advantages

The PCB prototype assembly is a complex procedure. Although it isn’t a part of the actual circuit board manufacturing process, it is still of immense importance. We offer prototype PCB assembly because of their have undeniable benefits. Here are some of them:

● This kind of PCB assembly aids in analyzing the design and function of the PCB prior to the final assembly. This can prevent a number of errors in the production process by identifying problems in the early stages. This saves money, production time, as well as resources.

● It’s possible to check the feasibility of a circuit at the design stage. JarnisTech emphasizes the use of Design for Manufacturability (DFM) as a means of ensuring quick and accurate design output.

Prototype Printed Circuit Board Assembly Process Steps

Understanding the process of assembly for PCB prototypes is crucial in the estimation of the cost and other aspects before contacting an enterprise to produce prototype PCBs. The process of assembly is as follows.

Allocation of a specific 2D

It is the first step and begins with the allocation of a specific 2D barcode to every printed circuit board. The barcode is crucial in allowing any trace-back needed, and for this to be achieved, the barcode needs to be scanned throughout the assembly process. Important information, such as supplier information and the delivery of each component’s documents also are traced. Additionally, the actions are taken, the duration and the individual who was responsible for the process must be linked in details of the PCB specs and the BOM’s revisions.

Stenciling of the Solder Paste

It is the next step of the assembly process. It comes with equipment like a MEDL stencil printer, which incorporates the solder paste onto the circuit board printed.

Pick and Place

The final step is to place SMD components in the correct order. SMD components precisely with the pick and position machine.

It Follows the Exact Installation of Components

The inspection confirms the proper orientation and positioning components are in the correct orientation and position. ( surface mount technology) components prior to sending the assembled assembly onto the soldering process.

Reflow Soldering

The next stage in the assembly procedure is the printed circuit board is placed in the reflow furnace along with all the components that are needed. The oven usually has various zones and will ensure that the solder paste is hardened. Solder paste. It is important to keep in mind that using the solder paste that has an extremely moderate melting temperature is advised. It eliminates the possibility of causing damage to any PCB components due to the high temperatures associated with the process of soldering.

Another Stage of Testing

It is essential to conduct another inspection following the soldering procedure of those SMT components. It will allow for the identification of any possible defects in solder joints. Another side, customer specifications and requirements determine whether inspections are performed manually or by machine.

Insertion Into Through Holes of Components

This is the following step following the second examination. Through-hole components are positioned by hand on the circuit board, which is why you have to make sure that they are placed in the right orientation. Soldering is done by either a machine or by hand, but it is contingent on the amount of the soldering that is required to be selective.

Technical Edge-cutting

This is the next step after the introduction of THT components. Before starting, however, you have to decide if you want to use automated machines to complete the assembly or work manually. In the event that says you’re using machines, your printed circuit board be equipped with technical edges, which require cutting off following the complete assembly. However, it becomes imperative to separate the panel at this point if the PCB is supplied as a panel containing many single circuits. To ensure clean cutting of the edges, pre-cut V-cuts or break-out tabs break-out tabs early during the ordering process.

At This Point

once cutting off of edges of the technical components has been completed, The third round of inspection takes place. This is an inspection process that aims to confirm the position and orientation of each component to make sure it’s in the correct position. Besides ensuring top-notch edges, the inspection also ensures the quality of solder connections.

It follows as the Next Step Following the Final Inspection

In this stage, the PCB prototype assemblies are put in secure ESD packaging. It is essential to know that every assembly requires its own protection from ESD in its bag. However, if the prototype’s dimensions are larger than standard packaging, the assemblies are packed in anti-static foam.

Quality Control

The last stage before the packages are sealed to allow shipping is quality control. The sample is then examined optically to ensure that it is a PCBA sample is high quality.
