Compositepro,
My understanding is that plating racks are usually dipped in a liquid plasticized PVC (Plastisol) and later cured. Its primarily a dip coating process. So the question becomes "Does dipping coating process provide uniform, precise tolerances for Si Wafers to sit on?"
Hi,
I am researching materials for Plating Racks/Jigs. The racks will be used to carry very delicate Si wafers with a Seed Copper layer. I am looking for a exhaustive list of materials (for both conductor and insulator) that are comaptible with:
Acidic Copper Plating solution
Acidic Tin...
Thank you both for the replies. I have contacted Dupont and other plastic manufacturers about the chemical compatibility. They are using "Chemical Resistance Guide for Plastics" by Compass Publications as reference. I have access to that book too. But we are having a discepancy between what the...
Hi,
Hi,
I have posted the same post at Chemical Engineering Forum. So I apologize for the duplication. But there was no response in that forum so I am posting it here.
I am looking for compatible plastics (PFA, PTFE, ECTFE, PVDF, PEEK, TFM) with:
1. 25% Tetra Methyl Ammonium Hydoxide- TMAH...
Hi,
I am looking for compatible plastics (PFA, PTFE, ECTFE, PVDF, PEEK, TFM) with:
1. 25% Tetra Methyl Ammonium Hydoxide- TMAH aqueous solution at 90 deg C
2. 25% TMAH solution in methanol at 90 deg C
3. 25% TMAH squeous solution + small amount of Glycidol Ether (surfactant).
I appreciate any...
Hi,
Thank you all for the wonderful advice. I am trying to play with the Animator/PhotoWorks to produce the animation. It may take me awhile to do it.
But starting this endevaor made me realize something ( most of you might already know this). I spend a lot of time thinking about the design...
Hello all,
We are Automated Process Equipment Manufacturer loacted in Bay Area,CA. We want to do a motion animation of our assembly which consists of 3174 parts @ 30 MB file size. But the file size of the folder that includes all the parts and sub-assemblies to open the assembly accounts to 262...
I have already submitted this post in another forum. I apologize for repeating it here.
We are an equipment manufacturer. We are using 2 axis Linear transfer for pick and place of the product. The vertical axis has brake motor and we are controlling using a PLC. Whenever we are disengaging the...
We are an equipment manufacturer. We are using 2 axis Linear transfer for pick and place of the product. The vertical axis has brake motor and we are controlling using a PLC. Whenever we are disengaging the brake, to start the vertical motion, the robot is free falling for 1/4" before the...
He said it makes it easier for him to read if it is on the RHS of the screen. I don't know if its true or not. Just trying to accommodate as much I can.
Cheers,
CBL,
The problem is interminent. It looks like the subset of the parts that are getting dropped is decreasing. I have created some new test assemblies just to test dragn drop. The problem exists independent of the assemblies. Yes,all the computers have same SW and SP. Yes the rogue computer is...
Hello,
I think I have seen this somewhere on the forum but unable to find the proper thread.
My question is " Is there any way to move the Feature Manager from Left side to the Right side of the screen?"
I found a thread where in The FM icons can be moved from top to bottom by changing the...
Hello,
We have the our library components/ purchased components stored in the Design Library folder on a Server. We used to able to drag n drop the components into assemblies without any problem.
But now one of my designers is having a weird error while he tries to drag n drop some of the...
Definitely. And what a long and torturous marriage that has been between the "Mars based Science" and "Venus based Economics" which left the "Earth base Engineering" completely bewildered!!
Mike: I am glad that you liked it.
