Circuit Board is very important to your project
All electronic products is assembly circuit boards.The circuit board is the foundation of our electronic products, and is the most critical component affecting long-term reliability.
Is this words find a high quality PCB manufacturer is very important.
Since most companies depend on manufacturing partners to fabricate the bare boards, we must:
Select suppliers who are capable of delivering the required level of quality
As above descript,circuit board is very important to your projects.If you just consider the cheap price PCB manufacturers,you may pay for more money when the project have some problems.
Specify the minimum level of acceptability for circuit boards
This point may confuse some people.Even some guy think this point is again to first tip.
To be honest,Jim also confuse at the beginning,but if you learn the detail you will change your mind.
Minimum level is doesn't equal to low quality.
So we must understanding minimum level of acceptability to PCB project cost control.
In this word,minimum level of acceptability is the low cost PCB option.
Perform checks to ensure that the boards meet the expected reliability
Last but not the least,if you have follow above two point,you may choose the low cost and high quality PCB suppliers.But high quality is just your PCB supplier say.
How you judge the PCB quality or how to control all you purchase PCB from you China PCB fabrication is OK?
Perform checks can help you handle this issue.
On the other hand, cost is an important issue, and we don't want to impose expensive and unnecessary tests to prove the acceptance criteria. Our goal is to derive the maximum level of confidence for the minimum amount of time and expense.
When determining the level of testing, we should err on the side of caution. One mistake can cause a line-down situation that results in an inability to ship, which can create scheduling and delivery problems throughout the organization. One defective product can damage our reputation and in severe cases, de-value the company brand.
The cost of recalling or scrapping assemblies is always higher than the cost of scrapping bare boards, and the cost of scrapping bare boards is always higher than the cost of proper inspection and process controls along the way. With this in mind, a small investment up front can prevent a catastrophic failure later on.
