PCB assembly costs

PCB assembly costs The math is almost apparent at this point, and the procedure for determining how much is each point is easy. But first, let’s define “point.” Different businesses employ different algorithms, but the ultimate PCB assembly cost for a PCB board is the same.

The basic goal of SMT assembly is to solder the electrical components to the PCB soldering pads. Some firms consider one pad to be one point, while others consider two pads to be one point. This article will count one pad as one point for the sake of clarity. All you have to do now is add up the number of pads on the PCB. However, some unusual components, such as inductors, huge capacitors, and integrated circuits (ICs), necessitate extra computations.

The specific experience approach is as follows: for example, the inductor is worth 10 points, and the IC is half-priced based on the number of pins (a 40-pin IC counts as 20 points). You can easily compute the total number of solder spots on the entire circuit board using the approach described above.

It is challenging to develop a quality product at the lowest cost. PCB assembly costs The quality of a PCB is determined by its craftsmanship for assembly, testing, fix, reliability, manufacturing, and yield. Several variables affect the cost of PCB assembly.

However, PCB designers may have to take into consideration variables that can reduce the cost of the PCB, like eliminating the PCB complexity, using fewer components, selecting cost-effective material

ls for PCB, etc. Depending on the PCB Fabrication, there is almost no power to reduce the assembly cost. Therefore, the focus should be put in the PCB design from the very beginning to reduce the PCB manufacturing cost.

Taking into consideration producing large volumes of PCBs, selecting panels for mounting PCBs, and finishing the right PCB surface can help lower the cost of production. Following the standardized procedures during each stage of development will help keep the overall cost in check.

These recommendations are being offered to lower the expense of the PCB Assembly costs without overriding the quality of the PCB.

PCB Assembly costs :Create an efficient Bill of Materials

A bill of materials is used for the component purchase, inventory planning, and tracking. A good bill of materials has all of the relevant information, such as the manufacturer’s part number, quantity, alternate part details, reference designators, and so on, which can help you save money on assembly by ordering in bulk. BoM also shows the lead time and lifecycle status of each component, preventing delays and lowering production costs.

Make a detailed examination of the context before determining the placement of the components.

It is recommended that all key component placements in a PCB design undergo a rigorous review based on their accessibility for soldering and rework. Place small parts away from bulky components that may necessitate hand soldering and raise expenses. Consider the soldering procedure utilized during assembly when making component placement decisions. By putting all of the SMD components on one side of the board, the PCB will only have to go through the pick and place procedure once. The stencil cost is reduced when the number of iterations is reduced.

Adhere to the Design for Testability (DFT) guidelines while developing the printed circuit board (PCB) design.

Clearly mark the Reference Designators on the bare printed circuit board(PCB)

This is a fantastic tip for lowering PCB rework expenses. If all of the reference designators are properly labeled and located near the associated part, the contract manufacturer should be able to provide a lower assembly costs.

To decrease assembly errors, it is recommended that small packaging be avoided. It will be difficult to provide clear reference designators for such small packages. Using 0402 packages for resistors instead of 0201 packages may appear small, but it saves about 10% on assembly costs.

Include the DFM guidelines in your layout design.

An improved layout design can significantly enhance PCB quality while simultaneously lowering assembly costs. The following are some suggestions for lowering PCB assembly costs:

• Selecting the Right PCB Substrate
• Standard board dimensions and thickness can be selected by the user.
• Create designs that require a minimum of a board layer.
• Insert a smaller number of connections.
• Include orienting aids such as fiducial markers.
• Choose the best PCB surface finish.

Consider making PCB assembly costs in the form of panels.

If you have a large manufacturing demand, paneling the PCBs is a great way to save money and improve assembly efficiency. During the assembly line’s pick and place stage, fiducial markings help with proper alignment. PCB Panels significantly minimize the PCB assembly costs runs.

Create a cost-effective procurement strategy for all of the components.

This begins with the PCB’s efficient BoM creation. Alternate part sourcing information should be included in the procurement plan. Check the component life cycle to guarantee that the part will be available throughout the PCB manufacturing process. Keep an eye on the lead time and put large orders. These procurement criteria will significantly minimize assembly costs.

Streamline the PCB development cycle by using modern Computer-Aided Design and Manufacturing (CAD/CAM) tools.

Many advancements in CAD/CAM software have aided in properly structuring the design flow and lowering costs. The availability of a comprehensive component library cuts down on rebuilding time and effort. Comprehensive design reviews can be driven by team collaboration software to increase product quality.

Emphasize the need of examination.

One of the most important aspects of lowering assembly costs is inspecting the bare circuit board. Basic checks such as PCB thickness, PCB surface finish, board warpage, and so on are covered by the manual inspection. Track shorts or openings, missing components, and other flaws can all be detected via automated visual inspections. Detecting faults early on can help you save a lot of time when it comes to debugging. A thorough inspection of the bare board before mounting the components is an excellent way to cut assembly costs.

Select a seasoned and dependable PCB contract manufacturer.

With all of the above suggestions for lowering PCB assembly costs, selecting an experienced PCB manufacturer is critical. Researching the background and expertise of the assembly supplier takes time, but it’s well worth it because some of them have technical teams to help with:

• Standard BoM formats are available.
• Support for Electrical and Mechanical Design
• For component purchases, there are several options.
• Test setups and debug support that is well-organized
• Assembling and manufacturing expertise

Depending on the projected turnaround time, several contract manufacturers provide different pricing choices. If your product is well-planned, giving your contract manufacturer enough time to complete the assembly can save you money without sacrificing PCB quality.

PCB SMD

A surface-mount device, often known as an SMD, is an electronic device in which the components are installed or placed directly on the PCB’s surface. … The through-hole technology building method of fitting components with wire leads into holes in the circuit board has mostly been supplanted in the industry.
