Are industry time standards based on actual time...or money? From a start to stop time on a multi-machine SMT line our time is well below standard. (Our company uses industry standard (I'm told) based on .09 sec. per placement.) However each pick an

We are printing on an assembly using SAC305 Alloy Sn96.5 Ag 3 Cu .5 with a no clean flux and getting virtually NO spread with either a ramp to spike or straight ramp profile. We are printing to standard FR4 board with immersion Ag finish. I am trying

Vinit- The name's Rick by the way. Probably best to stay in the new equipment business as your knowledge of used prices is a bit out of whack. First of all you could buy (2) CP4-1's new for what and FCM went for new. Second CP-4's are selling for ar

Q1) Simple way to measure the PCB warpage A1) IPC-TM-650; Method 2.4.22 Bow & Twist Q2) What is the maximum warpage can the SMT machine allow the to accept and place the component without problem. A2) That depends. IPC-A-610 Acceptability of Elect

Hi, There are a number of things you can try. You are already using 1:1 hole to pad ratio, and that's good as you need the size. I would try an electroform stencil as that will have a smooth side of the aperture and help paste release. Don't use c

Or you can use the Hot Air (Hakko) to remove that component and a tweezer to pull it. dont pull it just yet. If you see the solder melting then feel the component using the tweezer by wiggling it a bit and if you can wiggle it only then you can pull

I completely agree with the both of you, and mgmt. has decided to go that way. Cost, I pleaded, is negligible when compared to the addtl. work/headache of working with an additional adapter. Let me drag this further off-topic if I might...I've read

I have never seen a published "industry standard". What I've experienced with Fuji CP and IP is less than 1%. If feeders are changed over 3-4 times per day that will certainly add to this number. Not to mention sloppy operators. Some machines consume

Dear Patrick, Unfortunately we do not know what exactly the failure as our customer refuse to reveal to us. From visual inspection the solder joints are smooth and shiny as per IPC-A-610 requirements. The component supplier (IR) commended that they

It's interesting that your company was willing to buy enough machines to complete 4 lines, but isn't willing to buy enough parts for them to operate. That sort of reduces your 2-4 lines to a role of emergency spares locations, doesn't it? We experie
