Their response time here has been excellent. Then again, their main US office is only an hour away from us, so, that may skew my opinion of their response time. Cost is average. Around $120/hour, plus travel and parts. Registering is an issue. T

It's all by feel and looks. Too many variables to tell you exact number of times. Most profile boards are set up to perform initial profile and then repeatability at a set period after that. So changing boards will alter the t-couple and skew your

You can calibrate it until you are purple in the face. Job to job and part to part they are just not consistent.They either fail parts or put them on skewed. I have gone back and fourth on this for(10+) years. We have had Fuji look at it and we have

I've gone round and round on this very subject with our manufacturing engineer. He prefers to use panel fiducials and I prefer board fids. I've seen the result in placement from bowed PCB's in the machine. Skewing the board a fraction will throw off

One diagnostic tool that I have found useful in the past is the "hot plate test". Place suspect components and/or PCB's on a hot plate and turn it on High. Then observe. Granted the conditions on the hot plate are not the same as in a reflow oven,

We have an opportunity to purchase a Yestech YTV-1000 AOI machine. I am looking for opinions on how well they work and how they compare to the newer Yestech B3 AOI systems. We are a high mix, low volume EMS company. We do not currently have any exp

IP3 camera calibration, you need the following: 1. Part camera resolution Jig. 2. 10mm nozzle for nozzle centering. 3. Button jig (skip). 4. Glass board and Glass parts. 1. Conduct the Camera resolution. Set the following Delta values: X=+/-0.1mm;

I'm looking for a typical SMT placement defect rate from others in the field so I can judge whether or not we are in an acceptable range. If I give you a board with 200 components (0603, 0805, SOICs, 20mil MSOPs, tantalums, DPAKs and a few 20mil fin

We just pulled a Speedline Accuflex printer out of storage. After programming a board and stencil, and calibrating the fiducials and everything, we do a test alignment and bring the board to print height. It is off. I've done it now with two diffe

We are about to do a second iteration of something we struggled mightily with last time and I'm hoping to at least make a step in the right direction. There are 12 of these parts on the board and virtually all of them required removal and replacemen
