| Not much, just watching Create KME place 0201's sort-of fun to see. (Nepcon East). | Talk about placement problems.......so small hard to see. | Wayne Hi ya' Wayne! Man! 0201's!! I started hearing about 0201's at the beginning of last year, a

| Hi ya' Wayne! | Man! 0201's!! I started hearing about 0201's at the beginning of last year, and remember thinking then why in the world someone would ever need a individual resistor or capacitor to be that dinky...I know there's a push to make

| Can anyone tell me if there is a reference for smt component height specs on the bottom side of a board, which will also go through wave soldering. A current design I am reviewing has tant caps(7343) and a crystal on the back side. Should I only b

Help! We have been doing some trials on Paste Through Hole and have encountered a problem. The screen is designed (as is suggested in technical info re PTH) to give double the paste volume required to fill the void between the pin and via. The pro

A pad design shaped like Home Plate will eliminate the problem, You can get info from Create Group at Panasonic FA They have the patent on this style pad and the most experience working with the 0402 and now have qualified the 0201 Caps from Murata

Hello, We are currently trying to design and ultimately implement a system that will be able to count and manage component placement for three Sanyo chipshooters on three SMT lines. As the number of components decreases in the reels we want to be ab

I've heard of reliabilty problems caused by wave soldering melf's as well. We don't put Melfs on the bottom of our PCB's on newer designs. We only have to deal with gluing & putting them through the wave on some of our older legacy designs. Increasi

The main criteria is at what frequency is the RF operating? If it's in the microwave region, forget no-clean. Low frequencies - 0 to 100 MHz, probably ok. Beyond that, it's application specific. Depends on components used and circuit design. The p

Via in pad is the most efficient use of space. Blind via seems to be blamed for this. Cross-sections (send me some) will probably show a void still existing in the via or spherical voids aligned near the component pad side. One can estimate the vo
