yes, in old age Z motors do fail on the machine. also, the spring I am talking about is in the rack assembly. there is a split gear which engages the motor gear and it has a spring which maintains constant engagement with the gear. it is small and

I am looking for eveyones opinion on this cleaning process. We currently have both inline aqueous and batch for cleaning both water soluble, rosin and no clean fluxes. We have evaluated the vapor degreasing cleaning process and discovered equal if

I would be looking at used or refurbished equipment with that budget. We had a similar budget a few years back and ended up purchasing a rebuilt pick & place machine. We have been extremely happy with the results Don't forget that you will need t

What is your plan/budget for your reflow oven and paste printer? Those are equally important as a placement machine. Have you factored in other costs of in-house assembly such as inspection, moisture sensitive device storage, rework tools, cleaning p

Thanks for the comment regarding the CPH. In fact, the benchtop oven we have takes 7 minutes to complete a batch soldering, so you can imagine that our production volume will not be very high. We can parallelize PCB assembly and oven phase. But defi

We have a PCB to be populated using reflow soldering. The board contains lead free BGA device(11x11, 1mm pitch ) and Standard SMT devices which are not lead free. Since profile temperature is different for both devices, our contract assembly house is

There is a method and let me stress that you need a competent wrench man to do this.It does require a "crows foot" jig that you can probably get from a used equipment dealer. The proper way to clean the clutches is to remove them from the ring gear.

There is no 8mm wrenches involved. The procedure is a little to extensive to post.The only hand tools required are the crows foot jig a set of allen wrenches and an adjustable wrench. You have to remove the shaft crown to get the clutch out. Again..
