Pete C We do bake our tray parts. I am familiar with the ipc specs. The problem is for example: a level 4 component can only be out a total of 72 hrs before rebake is required. If this is a tube or reel part, the 125c bake temp that is recommended wi

Hi, why don't you call tech support of the manufacturer of your vibratory feeders.They will be able to help you.This is mostly a trial and error kind of adjustment and there are various "tricks" that I've noticed in various assembling plants (i.e. ke

We currently use Siplace P & P machines and in the main prefer to pick SOIC ICs from stick vibratory feeders. Our reason for this is that we can fit 3 stick fed devices into the same space as one reel fed SOIC. This reduces the amount of setup we hav

Had a similar problem on a high speed drilling machine. It took 1 month before I found it. In the leadscrew ball nut, there was a guide tube which the balls circulate through. at the end of the tube is a shaped lip. This lip was damaged and the balls

Chunks, Nozzle unfriendly? Maybe it should be called nozzle hostile. Depending on the machine and lighting a nozzle with a 1.8mm tube might work. In English units that would be a .072 OD with a .062 ID. The area such a nozzle would pick from is the 6

I noticed on the floor that workers hand place some SMT parts becuase some parts that came in a tube (instead of on a reel) do not fit properly into the tube feeders. The tubes dont align properly in the feeders becuase of their size. Are there any

We currently operate a procedure of keeping fresh tubes of solder paste in a fridge. When it is required we remove the required quantity from the tube and return the tube to the fridge before it warms up to room temperature. We then store this at r

A rejected part from a reel is a little bit of a pain to use, where a rejected part from a tube is easy. That doesn't mean that I like tubes though. I have also found that some parts cost more when delivered on tape. First check that your machine is

Hello, we have an Ekra E4 that we bought used and the stencil wipe never worked. We found that the air tubing for the up (black)& down (blue) of the wipe roll is missing. There are 2 push connectors for up and 2 for down to receive the tubes. Does an

Everything rob said makes perfect sense. That said, do you have a robust, infallible paste management system? ;) Have you tried multiple tubes and multiple date codes of paste and had the same results? Is it stored properly (on the tip, assuming i
