ES Industry Time Standards

Taking the machine cycle time is acceptable, to add in the odd occurrence, you need to manually time the 'minor stoppages' and do basically a guess as to how often it occurs. Take the stoppages time and divide that by the number of parts you expect to get between occurrences and add that back into the machine cycle time.

That should work just fine. You may need to adjust that over time as you get better data as to the number of stoppages you get.

Thanks for your feedback. I hope you are also from the EMS industry, on going thru' your reply.

I appreciate your comment that the time prediction from HLC is good start and understand that it may not be achieved in reality. But the reasons for not achieving the same, from my viewpoint, is the inefficiencies of perhaps the Management or the Operators. My opinion is that the Time Standard for the same should be in accordance with the HLC. But to start with, we may set the target by including certain allowances and cutting it down on yearly basis. The responsibility for improving the inefficiencies should be with the Process Engineer.

Regarding your remarks in para 3, what I have understood from the Service Engineer of the machine manufacturer (and is widely true with various types of fully automatic machines in various industries) is that deviation from the machine suggested feeder position is accounted in the cycle time shown & it will correspond to the actual placement of feeders in our machines. And the placement speed is also determined by the machine from factors like component size etc.

Your feedback to my opinion is invited.....

To start with, Take your set up time and divide it over you lot size. Then take yourmachine standard times and multiply by 0.85 Most operators are your slow downs and nobody works at 100%. 85% will leave you enough time for jams, misfeeds and operator error.

I have not found any standard times for hand insertion but i quote based on a couple of things:

Prep the kit

Form the part

pick up & orientate the part

Insert & clench

Avg Axial part 15 sec

Avg Radial part 18-20 sec.

You can figure this in your head, Imagine the part, pick it up and imagine inserting it 1-2 leads at a time, turning board uver and clinching.
