Terms of advice: There ought to be an audit of downtime information currently being logged by operators. Everybody must be on the exact same page and know how and when to log specific good reasons.
Dr Lasky provides a site and has some posts on this topic. If I have enough time I will try to look for them afterwards. Realistically it is possible to count on a no excuses utilisation price all-around 15%.
Hi Processman, The place I labored ahead of, being an SMT Office Chief, there have been two much more departments who ran SMT lines, and we had a process within the CEO to choose to how we measure our performances. The result was like this: - To begin with, you'll have a changeover time for every merchandise. Based upon your small business, machines and complexity from the machines, you need to determine a 'lawful' average changeover time which isn't regarded as downtime. Most of us labored within the 3 SMT departments with ASM Siplace machines, so we made a decision this authorized changeover time and energy to be 30 mins (interval of measurement of the time was last board at entrance of oven from 1 job, to the very first board at entrance from the oven of the next work); - 2nd, there will normally come about compact/significant complications over the line, so we reported that only All those downtimes will probably be investigated 1st, which are more substantial then ten minutes (similar measurement position, oven entrance; time difference between two boards); - third, we described together that point expended on new merchandise (sample creation), which operate within the line for your quite initially time, not to be regarded as downtimes, as we completed process optimizations, situation research of latest elements/tooling and planning creation strategies for serial creation; - fourth, prepared maintenances will not be downtimes (our decision) given that they are prepared, and when performed while in the given timeframe (our case, 1 shift) then it is legal.
Details Sheet M10 Direct absolutely free Reflow oven is specifically designed for mid-significant volume output. 10 higher and ten bottom pressured very hot air convection zones make it possible for superior quality guide-free of charge soldering with uniform heating and exceptional course of action security Temperature precision of ±1°C, ensure the best temperature Management across the Printed Circuit Board Assembly
FR4 product at superior frequencies has a relatively high dielectric frequent having said that, it can be used to fabricate HR PCBs when it really is combined with other superior frequency laminates. Other elements employed for top frequencies boards are:
Can solution CCD+displayer can exact positioning and soldering quality Look at. The Z axis is managed by a stepper motor and can be preset to soldering stress. Machines are created to buy therefore, orders are non-cancellable. Share:
You can feel it just after I discover the blog site posts. Needless to say All people takes advantage of some Variation of "but You can not count that point" technique. I discover Nearly All people thinks concerning measuring the operators performance. I believe that is very much the wrong way to have a look at it.
One other challenge with controlling by spread sheets is individuals learn to Participate in the game. Engineers and Mangers will fudge the quantities to help make the graphs seems to be excellent to their bosses.
15%? Now I'm curious to see the website. I understand everyone plays games Using the get more info quantities to back again into a thing satisfactory to management, but fifteen% would seem outstanding reduced, Even when you issue out the BS. Hope you find it, my google-fu wasn't ok.
The Combo Loader, masses your creation line quickly, It is provided with two PCB loading modes and especially appropriate for single-line mode which procedures double-sided PCBs.
The most critical actions that affects the finished good quality of circuit boards is the application of solder paste, Solder paste software is The real key course of action in board assembly operations applying SMT strategies.
Considerable money and time is used to produce Completely ineffective information and facts and everyone is happy to obtain it. From time to time I think I should really get in the MES/ERP business. I can publish program that does absolutely nothing useful and I can do it less expensive compared to the competition!
Are we talking about this 1 & posted on listed here not that long ago ? I run a small line carrying out minimal quantity runs, the "utilisation" might be close to as low as it might get. But I might wrestle to locate a strategy to outline it as low as fifteen% on anything at all but one of the most advanced builds with superior part combine as well as then, that is a alternative we have built based on the worth with the product or service, the gains we'd make by acquiring 2nd/third operator perform some guide stuffing, possessing more feeders to prep much more of those products and solutions ahead of time and so on. We Price this into our estimates, those self same assemblies are quoted on by Many others but we are the ones developing them.
This convection reflow oven is ideal for mid-to-significant volume direct-cost-free soldering production lines. eight higher and 8 bottom compelled very hot air convection zones enable high-quality lead-absolutely free soldering with uniform heating and exceptional method steadiness Temperature precision of ±one°C and a substantial-pace CE certificated blower for max convection
