Just wondering who should really operate an AOI? Should it be the SMT operator or the Inspector? We are trying to run the AOI inline but Operators do not feel it is their job to do so. Just wondering how others are handling it.

If it's inline then, operators.

"We are trying to run the AOI inline but Operators do not feel it is their job to do so."

THAN REPLACE THE OPERATORS WITH SOMEONE WHO VALUES A JOB. Thats how I would handle that one.

Most AOI, in-line or off-line, are operated by SMT machine operators.

Yes, and how dare they say "..do not feel it is their job". FEEL, are you kidding me. Fire their asses.

The operators likely feel it is a bit much technology wise for them as opposed to them being lazy about it.

Normally inspector is operating the verification station - such as checking the components found by AOI, feedback to the system about real defects and false calls, scanning barcode to find certain board, load data for the recipe and so on... Line operator making sure that the correct recipe and settings are loaded on the tester itself. It's also not complicated and can be done by inspector, but normally operator or line engineer does it to avoid using the wrong recipe or wrong version. All depends of how well is the data organized and what are responsibilities of different people in certain company. Vadim Shishov. Orbotech Pacific.

I agree with the one that says Fire them, but I do not have the authority to do so, but I know someone who does. I think our problem is that it is hard to find someone with SMT experience so we are stuck with what we have. Now if I was boss, trust me that is all I can say....

Are not the operators responsible for the quality of the product? Q.C. should not be responsible for assembling quality product they are there to ensure that the quality has been met. "Fire them"

"Firing" them is a big word......how about....maybe educating them to their job responsibilities. Now if that doesnt work, Send them to the unemployment office.

AOI should be operated by an INSPECTOR! Inspectors do not operate assembly machines or automated assembly equipment, why would an operator run an Automated Inspection? Are your operators certified to IPC standards to make calls on bad solder joints or skewed placement percentages? If they are educated to IPC standards then let them run it, if not then the ones who are trained and use these standards daily should make these decisions. AOI will catch mistakes, but who makes the decision if they are acceptable? Does the operator make this choice on their own judgement, which if it is incorrect who is responsible then?

Fire them has been stated on here several times. What exactly does that solve? I am assuming you have good operators, that you are asking to run an automated inspection, then what exactly are your inspectors doing? Are the operators going to get more pay for assuming more responibility? Sometimes it is easier to point blame at everyone else, then to truly resolve a problem. Maybe these people crying to fire them should be fired and then their respectable companies might have a chance of hiring true problem solvers.

AOI should be operated by a machine operator. I could get a monkey to stand around pushing buttons. A machine operator job responsibilty is not to change feeders and push buttons. They have to monitor the process for missing parts, misaligned, and paste despositon. Machine operators have to monitor this issues to relay them to engineering group to fix them before they even get past the oven. It is cheaper to fix the problem than to rework it where you can have the potential to lift a pad or damage a board. It is a lot easier to wipe the board clean and save all the high dollar parts and rescreen. So the machine operators should be knowledgeable in IPC and capable of making those critical decisions pass or fail and they can use that AOI as a tool to monitor and check their job and process if it is running smoothly. Too many operators think they are too good to take on other job duties. I once supervised a line and when a operator put in a wrong part the entire line gets to do rework and not depend on the rework person to fix your mistake. Like you getting sum1 else to pick up after you. After that very few mistakes were made cause they know what happens when the operator causes a defect.

Have all of you "Fire Them" type mentalities ever herd the old addage "Never tech your own work"?

Inspection should be done by inspectors.

I worked at a place where the new manager wanted SMT operators with experience. Two of the operators were pretty much as good as all the others put together. They had no SMT experience when they started. The company was lucky they started before he was hired. Requiring SMT experience sounds good, but hiring trainable people and having decent on the job training is usually better. Although I think a mix of people with outside experience and raw recruits is best.

Good point tommy, I think we are confusing what we are talking about here. It was not asked if the operators should do inspection. It was asked if an operator should pass boards through a machine. The operator is not inspecting anything just as they are not building the board either, the machine is. Q.C. would be valuable to validate the failures and disposition of such and implement the corrective action to resolve the false calls. I have never been in a company where any one that is involved in the production of an assembly has not been trained to acceptability standards. I would not want a machine operator placing off pad BGAs into the oven because they didn't know and let the Q.C. after reflow tell them that we now have rework. I also do not accept "it's not my job" Quality is everyones job and until this mind set takes hold we will continue to fail in this industry.

It's easier if the Operator does keep an eye over that, HOWEVER, if you really think about it, you are allowing the very person who ran the board monitor the quality of the board (again, re-visiting AOI errors, and what they allow and don't allow). As we all know, there are some operators out there that really don't care too much about the 'quality' they produce, rather, how many they can produce and when break time is.

I think that if you allow an operator do the AOI, you loose that 'check and balance' measure.

We are looking into purchasing an AOI sysstem and will have the operators run the system. With the right training our staff will do a great job and it will make their job easier. Currently we are relying on the Mark II eyeball. As for inspectors we don't have any dedicated positions. It is clearly understood that we all act as inspectors and operators. We haven't had dedicated inspectors for two years now are reduceing the amount of errors every month. Calculating Sigma we are rougly around 5.4Sigma for quality as measured from our board test area. Prior to doing away with the dedicated inspectors we were roughly at 3Sigma or less, becouse the prevailing belief of our staff was the inspectors will catch it. Just my two cents. Jay Brower

Agree with some of the prior postings, disagree with most. This is obviously not suitble in every plant/company/country:

We have some AOI:s inline and 1 off line and the "so called operators" is happy to be able to get to the next step: an improvement of their already good workmanship and beyond.

How about good company behavior, including proper training to the employee, so they at least get a chance to do their best? /Sincerely

In general, the operators know what is expected from them, but, to be fair, they should also have the IPC training to back them up.

You're right! Whether "Pattern matching" or "Pixel recognition", in both cases, it is the operating person who will make an inference from the results obtained. This makes IPC knowledge the key to AOI usage.

"Quality" is never introduced into a product though Inspection, but Processes can only be controlled using such equipments. The most ideal case would be a NO INSPECTION scenerio. I feel, one should aim to achieve this goal.
