| B0101 | Hi azonenberg | 01:22 |
|---|---|---|
| azonenberg | hi | 01:22 |
| B0101 | about the wafers... | 01:22 |
| azonenberg | yeah? | 01:22 |
| B0101 | they are prime wafers | 01:22 |
| azonenberg | Four inch prime grade for under USD 10? Polished on at least one side? | 01:23 |
| azonenberg | quantity one? | 01:23 |
| B0101 | yes | 01:23 |
| B0101 | and polished | 01:23 |
| azonenberg | Definitely put them on the wiki lol | 01:23 |
| azonenberg | thats the best price i've ever seen | 01:23 |
| B0101 | the price is so cheap because the universities of Singapore are funding them | 01:23 |
| azonenberg | i paid around $35 for a 4-inch prime grade from MTI a few months ago | 01:23 |
| azonenberg | I see | 01:24 |
| azonenberg | So do they only sell to educational customers? | 01:24 |
| B0101 | any customer | 01:24 |
| azonenberg | even outside singapore? | 01:24 |
| azonenberg | Not that international shipping would make it affordable | 01:24 |
| azonenberg | But for anyone in the area it's an amazing price | 01:24 |
| B0101 | I don't think that they ship outside SG, but I will check | 01:24 |
| azonenberg | Doesnt matter | 01:25 |
| azonenberg | Put it on the wiki anyway | 01:25 |
| azonenberg | if you havent already | 01:25 |
| B0101 | they also have lab equipment | 01:26 |
| azonenberg | very interesting | 01:26 |
| B0101 | here is their site: http://www.latech.com.sg/ | 01:27 |
| B0101 | yes they ship to other countries as well... | 01:28 |
| azonenberg | But i expect the cost of shipping is such that buying locally would be cheaper | 01:28 |
| azonenberg | At least to the USA | 01:28 |
| azonenberg | for nearby countries it may be feasible | 01:28 |
| azonenberg | like i said, definitely a valuable resource | 01:28 |
| CIA-67 | homecmos r118 | wiki/Vendors.wiki | Edited wiki page Vendors through web user interface. | 01:30 |
| azonenberg | lekernel: what package is the fpga on the milkymist? | 01:32 |
| azonenberg | i know it's a spartan-6 in some kind of bga, but what pin count? | 01:32 |
| azonenberg | (and what pitch) | 01:35 |
| B0101 | Azonenberg: do you use Ge wafers? | 01:35 |
| azonenberg | B0101: I have not tried working with anything but Si yet | 01:35 |
| azonenberg | lekernel: i was looking at getting an XC6SLX25 in 256FTBGA, i think i can handle routing the pins i need on 4 layers (I dont need all the IOs but they dont offer it in a QFP package) | 01:36 |
| azonenberg | do you think its realistic to try toaster-oven soldering of one? | 01:36 |
| azonenberg | on a 4-layer board with soldermask | 01:36 |
| azonenberg | the pitch of the 256FTBGA is 1mm | 01:37 |
| azonenberg | nice and big | 01:37 |
| azonenberg | i was thinking of getting a cheap one like http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=122-1542-ND first | 01:38 |
| azonenberg | to test the process on | 01:38 |
| azonenberg | but it isnt pin compatible so i'd need to make a separate board to test on, which kinda nullfiies the savings | 01:39 |
| B0101 | Alienware wants to work with me?! O_o | 02:06 |
| Anarchos | hi everybody | 19:33 |
| Anarchos | what is the purpose of homecmos ? | 19:46 |
| berndj | Anarchos: semiconductor fabbing with kitchen chemicals | 22:20 |
| Anarchos | berndj wow | 22:21 |
| berndj | maybe not quite, but without requiring a billion dollar plant | 22:21 |
| Anarchos | i am just looking for standard cells library for Gnu Electric | 22:21 |
| berndj | do you use electric a lot? | 22:21 |
| berndj | it sure has nice screenshots, but a) it had too many dependencies so i gave up building it, b) i hate anything java! | 22:22 |
| Anarchos | berndj i use electric as a hobby at work when i am bored with J2EE | 22:23 |
| Anarchos | anyway i just use the binaries | 22:23 |
| berndj | do you make chips for a living? | 22:25 |
| Anarchos | berndj not at all | 22:30 |
