Alibaba provides a great service with its trade assurance. Its only a few percent of cost and provides a good level of assurance. The vendor knows they will get paid, and the buyer knows that if the vendor doe'st deliver that they won't be stung. It also means you dont' need to worry about all the hassles of checking out who the company is, as alibaba does all that. I have used this many times with a lot of companies, and it just makes it work.

Some months before I thought about to add this function to our PNP machine.
But there are some more complicated things to solve.
You need to add more than one camera from minimum 2 directions and light from different directions if you want to inspect the solder points too.
It's easy to detect if there is a part or not but solder point inspection is more complicated.
Your machine has free dispenser unit installed I hope this could be nice for you.

They wanted 50% with the order and 50% before shipping. I went to my bank and wired the
full payment (to avoid the additional bank fees). It takes a lot of faith and courage to wire $15K to a company in China! Not only that they wanted the payment to be deposited in some unknown Chinese guys account (the real owner???). They acknowledged the payment on Feb 21, 2019 and told me the machine went into production an it would ship in 6 weeks...

I just replied to an old post about DIY AOI in another subforum and realized that it would propably be more relevant here:QuoteQuote from: Smallsmt on March 31, 2016, 06:10:07 am

Instead of multiple cameras couldn't the first step be to use the camera that is already there and change the position to get different angles?
The idea is to use the aperture angle of the camera to create different viewing angles.
In the center is is straight down and in the four corners you have the maximum viewing angle.
Example with 2 90° angles: position below left of pad and use upper right of picture, position upper left of pad and use lower right of picture.
Example with 3 90° angles: position below pad and use upper picture, position left of pad and use right of picture, position above pad and use lower picture.
It should be possible to define inspection points for each footprint type in the library and offset them with the P&P file X, Y and rotation.
That would be a cool feature to have.

You're wrong we already discussed before.
And it doesn't depend on forum trolls!
You're so clever and takes more than 5% from seller for this plus a high member fee.

While i have no reason to doubt you are for real, Your not the person I am refering to.
Revenue,
Don't worry... I await Your review with baited breath.
It's a function of a dedicated AOI and we need the cameras from different angles to calculate 3D information for solder points.
We need multiple cameras to increase the speed too.
The simple top camera can only check if a part is on position but we want to know if it's soldered well too.
Feeders should be here tomorrow (Tuesday) However the machine seems to be stuck in Hong Kong....
At the risk of starting the ugly...why the constant acrimony?
If that is true...I'M SCREWED!
