"...but does the Quad have any sensing of what is going on in the feeder?" Not with the feeders we use. Same deal as the Topaz, i.e., the machine knows if the nozzle has a part on it, but doesn't know what is happening in the feeder. There are "smar

The feeders on the CSM84 actually feed the tapes forward by the force of a spring. On the 8mm and 12mm feeders the spring is loaded directly by the force of the push rod on the placement head. With the larger tapes like 16mm and 24mm, a stronger sp

The standard you need is EIA-481B. It details the taping of components from 8mm tape up to 200mm tape including component orientations. 8, 12, 16 and 24mm tape has the sprocket holes only on one side so it is easy to determine the proper orientatio

Hi, I have a general question about the relationship of PCB thickness and BLR testing result. For example, I have QFN6x6 parts mounted on board in 1.2mm, 1.6mm, and 2.4mm thickness. All boards have 6 layers of Cu. Studies show thicker board gives les

Hi all, * Defect : termial to terminal touching btw two melfs body that created short circuit. * Clearance : 0.8mm btw two melfs body. * Size melf : diameter=2.4mm to 2.7mm, length=4.8mm to 5.2mm * Stencil opening : "v" shaped to minimise component

Hello, I'm a student assistant in a research project that deals with the simulation of PCB assembly systems. At the moment I collect information about SMDs. My problem is how to assign the correct feeder width to various devices in a simulation. Is

Pneumatic feeders are fixed-pitch, which is quite OK for most 8mm tape parts (except 0402 and smaller). Multipitch feeders are electric and cost a lot more, so you should see what pitches do you need and is it worth buying MP feeder(s). We have 30% i

Main difference is the reel holder position and for sure the clamping pin location. Tape feeding system is different. Any way they cannot be compatible among them. Q type feeders must be used for MV Q-Type placer and K-type feeders must be used for M

we have a capacitor cracking on one of our boards, there are four of the same cap on the board and only one cracks, we are seeing about 6% of the component cracking. it's not near the edges of the board and he board is 2.4mm thick so i dont think it
