[labnetwork] Dicing Saw Advice.....

[Usha Raghuram]

We have been using DISCO wafersaw at Stanford for the last 5 years with minimal down time and over 300 users using the tool in that time frame.

Best,

Usha

Definitely disco. I had the competitive’s vendor engineers coming over to our facility to understand how Disco can be so good. The dicing experience is very convenient (after a rather short learning curve). The machine is very reliable and does not require much maintenance, if it’s not being abused.. i.e. good cooling water (preferably DI), weekly cleaning of the chamber, etc...

Best,
Youry

That photo of the MicroAutomation saw gave me some creepy flashbacks! I worked on a fleet of those about 25 years ago.
Two vendors come to mind, one being K&S and another being Disco. I have experience with both, but Disco has been the most developed and supportive dicing saw vendor.
Good luck,

Hi everyone, I’m hoping the group can provide some advice regarding dicing and dicing saws.

We have a refurbished (within the past 3yrs) MicroAutomation MA1006<https://urldefense.proofpoint.com/v2/url?u=https-3A__engineering.tufts.edu_microfab_capabilities_MA1006Saw.htm&d=DwMFAg&c=WO-RGvefibhHBZq3fL85hQ&r=-H4Z_jeDfTYjnKPXor15vLwzBllmg8gFrb9m_k9OGks&m=nuBi9zk2EtI6eQL594rhhH5VsjHUTxPycO_Gg5IDIM8&s=3PgdUx-pKubD7Vy0tdjZzybiPz87wKFgXWO_0GbQRMg&e=> saw which requires significant time/resources to keep online. Unfortunately, it is underutilized, only 1-2 dicing jobs per month. With such poor bang-for-the-buck we’re considering alternatives -


  *   A different service provider – maybe our support is subpar?

For those who have similar tools, who maintains them? What are your results?

  *   Purchase a different, hopefully more reliable saw

For those with other saws, what do you have? Can you comment on reliability? Consumable costs? Ease of use?

  *   Remove the saw and do not replace it

Losing capabilities is suboptimal and perhaps sets a perilous precedent (we are university lab, none of our tools are justified *economically*). Have others done this? Can anyone recommend a source for dicing services – specifically for small, infrequent jobs?

  *   Other possibilities we haven’t considered?

I’m eager to hear various perspectives and experiences.
