Has anyone heard of any software that can be used to clean up or manipulate x-y placement data. We are a small contract manufacturer with various customers, some who supply good x-y data to component centres and some who supply x-y data to a pin or

We are currently reviewing a design which has a leadless chip scale package with a solder thermal pad on the underside. The application notes for the device specify use of a no-clean solder paste as the gap under the device will prevent cleaning. Is

I've a query. I have one new Customer whom insisted us to use RMA paste on their product. The problem is, on some of their products they use via hole as the test point in where all the PCB finished are ENTEK and as usual I have to print solder paste

Have been trying to cut through Paste supplier 'Qualification' documents and sales blurb but when asked if they'd put their mortgages on the line, assurances are harder to come by. In God we trust - All others must provide data. Are there any previo

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.

I used to work with S15/F3, was a 10 years ago. 1. Test your machine controllers and station controllers. Load the last program with actuell command. 2. You can check what happening in the SiPlace, switch the monitor to MC, let see all bootup perfec

What is the difference of formulation No-Clean Sn63 with No-Clean lead free paste? Is there techniocal data in detail for performance property of No-Clean lead free paste (for example, viscosity, solderability, tack, print life, reflow profile)? Is

Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

I have struggled with this myself. Usually where the pressure to clean the residue off is from the people who see the residue but do not understand the characteristics. I have not found a reason to clean residue off. A few people from our design gro
