To All, I am looking for some feedback on the storage and handling of moisture sensative components. Mostly what people do for tubes and reels since most of these cant handle more than 60c.the ipc standard states that they can be baked at 40c.The onl

These are inexpensive radiation monitoring devices and it is possible, when they are calibrated to a Cesium-137 standard (at 600 keV), for the meter to read higher than the actual value at lower x-ray photon energies. [Glennbrook Technologies Caution

Yes, we have the Agilis stick feeder and it is a definite improvement on the vibe. It usually comes with a set of starter 'tubeforks', but i bought another starter set after a while since the individual tubeforks are relatively expenisive. Always g

There is the IPC/JEDEC J-STD-033 that addresses moisture sensitive components. Go to http://www.ipc.org for the standard. Your factory/storage area environment will dictate exposure times allowable. Be mindful of temperature and humidity changes- lik

Genny, you may want to look at the brds you will be running and identify the various packages. I do not know what a standard package is. Most chip resistor and capacitors, 0402, 0603, 1206, 1210's are on 8mm feeders, but ic's vary quite a bit. Also r

| Does anyone have any figures on what % extra compnents should be supplied on chip components for a particular product build. Typicaly there is wastage due to dropout in loading, 1st board build and machine rejections. Is there any industry standard

Hello Peterson, If the contact tails protruded enough on the underside of the PCB, then you could do a "reverse" press fit. I do not believe that to be the case with the VHDM. Placement equipment is out of my bailiwick but; Usually small SMT connec

There is standard pick and place equipment such as the Assembl�on (formerly Philips EMT) ACM Micro and AQ-1 that can easily handle your snap-fit through-hole BNC connectors, in addition to other surface mount components and through-hole odd form part
