# What is the difference between yield and throughput?

## What is the difference between yield and throughput?

As nouns the difference between yield and throughput is that yield is (obsolete) payment; tribute while throughput is (operations) the rate of production; the rate at which something can be processed.

What is a yield in manufacturing?

Yield. It refers to the percentage of non-defective items of all produced items, and is usually indicated by the ratio of the number of non-defective items against the number of manufactured items. Yield = the number of non-defective items / the number of manufactured items.

### What is the rolled throughput yield of this 3 step process with yields of 90 each?

In a 3 step process each with 90% yield, your rolled through yield will be 72%, which is a huge amount of waste.

What is equivalent throughput yield?

Throughput yield (YTP) is the number of good units that are produced divided by the total number of units that go into each step of the process. Throughput yield considers the amount of scrap and rework in a process.

#### How is yield calculated in manufacturing?

Production yield is a metric that results from dividing the number of good parts produced divided by the total number of parts started in production.

What does OEE stand for in manufacturing?

Overall Equipment Effectiveness
OEE (Overall Equipment Effectiveness) is the gold standard for measuring manufacturing productivity. Simply put – it identifies the percentage of manufacturing time that is truly productive. An OEE score of 100% means you are manufacturing only Good Parts, as fast as possible, with no Stop Time.

## What is the difference between throughput and rolled throughput yield?

Rolled throughput yield (YRT) is the probability that a single unit can pass through the entire process without defects. When you calculate throughput yield, you count only the units that make it through the process without rework or scrap.

What is a good rolled throughput yield?

An overview: What is rolled throughput yield? Rolled throughput yield is the probability of a product or service making it through the entire process without having a single defect. Ideally, you want this value to be 100%, but that can only happen if all products pass each process step 100% of the time.

### What is CP and CPK?

Cp and Cpk, commonly referred to as process capability indices, are used to define the ability of a process to produce a product that meets requirements. Specifications: Specifications define product requirements. In other words, they define what is expected from an item for it to be usable.

What is the Rolled throughput yield of a cutting process?

The throughput yield of the cutting process is 88%. Rolled throughput yield (YRT) is the probability that a single unit can pass through the entire process without defects. You can multiply the individual throughput yields at each process step to obtain the overall, rolled throughput yield.

#### How to calculate the yield from a process?

There are two ways to calculate the yield from a process. If you are evaluating CMs for a project, make sure you look hard at the way they calculate yield on their production lines and how they use the results. (If you are a CM, in particular, use rolled throughput yield and make yourself a hero of cost reduction in your business!)

How to calculate the throughput yield ( YTP )?

You want to calculate the throughput yield at each step of the process. First, 1000 labels go to the printing process, and 950 of the printed labels are acceptable. The throughput yield of the printing process is 95%. Then, 950 labels go to the laminating process, and 800 of the laminated labels are acceptable.

## What are yield issues in the production process?

At that CM, yield issues at addressed at each step in the production process with improvement teams. A significant difference in the quotes received from the various CMs I visited was the circuit board testing schedule.
