Haven't noticed any major difference between C's and R's. Our biggest problem is feeders that will advance to the same location and leave the part in the pocket. We see "billboarding" on R's when the feeder isn't working right. If you have a good

Hi Jacky, It seems you have solder bead problem, beading occurs when the solder paste brick splatter as a component is placed into it, after reflow, the splatter becomes a spherical solder ball. Hope this will help. Steve USA STENCILS

Jacky, we have had a similar problem. We needed to go to a smaller nozzle and also check your vacuume system and air kiss.Could be after placement when the machine blows air to insure the part is off the nozzle that it is effecting the solder brick.

Short answer is - not really. According to the manual in Chapter 1-5 Supply devices (Feeders) overview "There are also available an 8mm tape feeder which handles 1005(0402) square chips". I have never seen one. The problem is that even an H nozzle is

| Does any one wave solder the 0402 Chips on the bottom side of a board? | Any comments? You will need to use a curable epoxy at the site of placement before placing the 0402--then cure the epoxy...possible problems are epoxy intrusion on the lands

Hi Grant, Murata do 0402 chip caps on 50K reels - example: GRM1555C1H101JZ01J 0402, 100pf, NPO/C0G 50V 5% (make sure the final letter is included - the J denotes the reel size - D is standard 10K) Rohm MCR01 series (0402 resistors) come on 6inch, 1

It could be a part height issue. I have seen a case where an 0402 resistor from 2 different manufactures had different heights. If the height of your 2010 part is taller than you have programmed in the package data, the pick up head may be pushing

Hi, We are running 0402 component on the TCM1000 and we find that teher will be missalignment on 0402 Capositor. We have identified that the missalignment is caused by the wrong information from the vision system while doing vision centering. The sy

Everybody aware of the tomb-stone problem on 0402 package. I've done everything I could i.e. Profile, placement, 10 Deg placement, stencil design, but still this culprit exist. One things for sure is taht I have a very bad pad size for 0402 ( 25 mil
