We appreciate your desire to find the most time effective method of reworking these boards. However, we believe that your most efficient method will be to have one assembler remove all of the parts, and a second assembler place/hand solder the parts

Philips (Yamaha) use a non standard NSK Ball screw and nut assembly. You should buy the genuine ball screw from your agent as the series of Ball screws used on these machines are the "NSK Super Precision series" which is not stocked by linear guide s

Let's be more specific. Why do you need to clean the boards? I assume it is for testing purposes, probe contact concerns and the like. This is the only economical reason I can think of to clean no-clean flux residue from your assemblies. Before y

So you are saying that building to class III is going to prevent failures? I disagree. Class III is trying to hit target condition in every aspect of the production of the circuit board. That my friend does not ensure failures from happening. I see

Here's two ideas fro the fine SMTnet Archives: * On the bare board, during design / layout, the basic shape of the jumper is a 125 thou disc of copper [that of course is eventually covered with whatever solderability preservative we use on the board]

If 3-5% of the attempted parts placed are dropped, you have a serious problem...that's 1 part dropped for every 20 or 30 placements. Does it mean that it drops the part in the scrap bin and then successfully places the same part or would the board co

Talk to your buyers about forcasts. How do they know how to what to buy? They should be able to tell you what parts are going to be used on all the upcoming assemblies. Just make sure you don't get a purchase requirement report. That wouldn't inc

You might try to complete all your soldering within a 72 hour or less time frame. For all intents treat your board like a moisture sensitive component after you have baked and completed SMT reflow. Wash, blow dry, and go direct to stuffing and com

We run a MY12 and our largest layout has 9700 components of which about 8500 (88%) are placed by the Hydra head. Average run time for our layout is 75 minutes. Based on that and depending on what percentage of your components are Hydra mountable, y

Hey guys, I'm new to this forum and registered to ask a question about PCB assembly cost. I was hoping to design a PCB that will be approximately 6" by 6" with about 1100 0805 SMD components on it. Half of them being resistors (3 different values) a
