Yes, it is basically: Rate = Time interval/Cycle time I put time interval since you can measure however you want (pc per hour, per day, per quarter hour... it is relative) the most used is Pc/Hour, so the time interval is 1 hour (3600 sec). Lets sa

Cost = Labor + Production Materials + Overhead Cost = Labor * Overhead Multiplier Cost = (Time For Task*Labor Rate*Benefits) * Overhead Multiplier Cost = ((6sec/3600sec/hr)*$10/hr*1.3) * 2 Cost = $0.04

SMT Experts, Hi, I have a pondering issue, which is : Our current specified Reflow preheat timing is a necessary 100~140sec for the ranges of 100~170Deg-C....obtained timing is 77sec... out of curiousity, if we further fine tune the obtained reflo

Profile would be the first place I look. Check your rise and fall rates for temp. Should be no more than 2 deg/sec for rise and 4-6 deg/sec for cooling. Phil

230C for max 30 sec.". Isn't 225C close enough to 230C, so that you are effectively exceeding mfg spec by 60 sec.?

We would benchmark our times with the most experienced operator and them boost the time by 1/3. Example: If it takes Mary 3sec to insert the component, 3 secs to clinch and cut the leads (it is not advised to cut the leads after soldering), and 8 sec
