John: Sorry I'm tardy getting back to you on this Heat capacity = [applied voltage in volts*applied current in amps*(time ending in seconds - time start in seconds)]/(�K ending - �K start) The units of heat capacity are joules per mole-degree when

Does anyone know of a handy dandy reference guide showing what the standard feeder tape size is for most common SMD packages? Just trying to figure out what the capacity REALLY is of all these pick and place machines I'm looking at, that state capaci

Tented vias have solved problems for me in the past, but never created any. I have heard seemingly pointless discussions about whether or not the EE that designed the board designed it with filled vias in mind (a consideration of current carrying c

Thanks Reese. Right at the moment we haven't ran into big capacity issues, but I can foresee it coming if we continue to grow. I was just looking for some other opinions from everyone as to how they handle process complications with older equipment.

Dear all, I'm looking for a new, complete and useful spreadsheet to perform some SMT capacity analyzes spreeadsheets. I have some samples, but I'm looking for the an improved, detailed and complete model. I'll really appreciate if you share some m

Running in series is best for less change-over, depending on how many components you use. But, as Dave stated, if you have the capacity on your machines to run your product on one machine, then you can do that and get twice the throughput. Series wi

Regardless of the design technology of the board, we use shop floor management software that: * Calculates the period that it takes to assemble a job. Obviously, we enter product-manufacturing information [ie, BOM, material receipt dates, process fl

Thank you very much for your reply. I do have the numbers for placement per hour, but, I have some concerns on it (forgive me if it is a stupid concern, as I said, I am new in this field, and trying to figure out this business). For example, it is

Mark, I guess while your machine sits idle, it could do boards. While the machine processes boards it breaks down by a certain percentage rate. I would multiply the placement rate with the idle time, multiplied by uptime divided by hundred. 10.000 (
