What Goes Into a PCB Board Assembly?

PCBA(PCB Assembly) It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It's these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

 *SMT(Surface-mount technology)
 SMT allows for higher connection densities and is typically faster and more cost-effective than through-hole manufacturing.the manufacturer mounts components directly on the surface of the board.

*Through-hole manufacturing
 Through-hole,or thru-hole,manufacturing is an older PCB assembly method that involves placing units in holes drilled in the board and soldering the leads to pads on the opposite side of it.The main advantage of through-hole assembly is the stronger bond between the components and the circuit board, which makes the product more durable. This method is more time-consuming and expensive than surface-mount technology but is necessary for products that will undergo substantial mechanical stress, environmental stress or high voltage. It's also ideal for larger components such as connectors and transformers.

*You can also use a combination of the two methods on a single product.

Following features for your consideration to choose a right PCBA manufacturer.

1. On time delivery with quality ensure.That will get your product to customers on time and maximize profit while minimizing expenses.The company that's right for you should be able to work according to your timeframe, as long as it's reasonable.

2.Professional

*Do they have experience with surface-mount technology, through-hole manufacturing or both?

*What size batches do they typically work with?

*What kinds of products have they assembled and what kinds of components did those projects involve?

*What industries have they worked with? commercial equipment/medical industry / telecom industry?

*What other services do they offer?Do they provide box build and final assembly as well as? 

*how long they've been in business?

3.Quality

*Equipment: What equipment does the company use? If they use top-of-the-line machinery, it's more likely they'll produce quality results. While it's not a guarantee, it can be a good indicator.

*Certifications: To earn certifications, companies have to undergo independent reviews by qualified third parties. This should provide you with some assurance that you'll get a high-end product.

*Client Feedback: The feedback a company has received is another good indicator of quality. 

4.Testing Options

Adequate quality testing is crucial because a failure can cost you time and money and cause damage to your reputation.

*automated optical inspections

*component-level checks

* in-circuit verification.

If a company has ISO 9001 certification or is registered with the FDA to supply testing solutions for medical device clients, you can have even more confidence in their testing services

5.Customer Support

Will they work with you to come up with a custom assembly and testing routine? If you're not sure which assembly technique will work best for your project, you might need this service. If you have technical problems with your PCBs, will they work with you to fix them? Can the company be flexible enough to get you the solution you need on your schedule?

6. Costs
Don't be afraid to spend a little more for higher quality, since the investment will pay off in the long run.The cost of PCB assembly varies widely depending on factors such as:

*Order Size

*Services requested:The type of service you request will also make a difference. Through-hole manufacturing and surface-mount technology costs can vary. If you need extra testing, need the assembly company to help you with design or need the firm to procure the components to be assembled, your costs will also increase.

*Resources provided:Such as provided the components yourself,this can be a more cost effective approach.

*Labor costs:More involved and advanced projects will likely have higher labor costs.

*Shipping costs
