The courtyard around a 0603 resistor should be: * 0.008" along the short edge of the component / pad * 0.036" along the long edge of the component / pad As you say, the component courtyard should be larger than the spacing between features, becaus

Does anyone have experience with the Heller 1088 Series ovens?? I am interested in their performance when used to reflow cards sized from 2"*4" up to 8"*12" All reflowed parts would be 0608 up in size and nothing like BGA's or pine pitch will be us

I'm using Kic Profiler and aluminium tape from Kic and thermocouples from Kic. They are good and reliable. I even manage to modify my heller 1088 by adjusting the fix conveyor and re-baffling the oven. Had dropped my 20-22 deg. C delta T down to 4.3

Well the only spec is 10.88% flux, 89.12% metal. the problem is only at one specific capacitor we have this issue. Sn over Ni finish. Sn-Ag solder paste. I have read all the arhives from the site, but nothing explains me what is happening.everything

We have an old (dinosaur, 1992 vintage) heller 988 that we use for shrinking heat shrink, curing, low temperature stuff. We need another similar oven for expanded production. Essentially any reliable, running, non-lead-free three four or five zone ov

Dear All, We plan to setup an assembly line for our small volume production of PCBs (about couple hundred PCBs per week). The board has about 150 components (less than 30 types) and a few BGA and IC (majority is SMT, only few THT connectors). We hav

I am most familiar with Heller (10 yrs. of 1088 4 zone - 1800 8 zone ovens) and find them to be very reliable. Other Manufacturers may have five zone ovens on the used market. (I used Petlock as an example because you could get data sheets/specs from

myu, Is using a 0.6mm stencil wise? 42.5 X 42.5 has two models, the 1mm pitch has 41x41 array with 1657 I/O and the 1.27mm pitch has 33x33 with 1088 I/O. For a typical c-cga with 1.0mm - 1.27mm pitch, may requires a 2mil stencil, 1.0mm pitch gets .

Hello, yes you are absolutely correct. I agree with your point. Last week,I personally checked out my board on Heller 1088 which is a 8 zone reflow oven (4 on top and 4 on bottom) and the soldering came pretty nice. So comparing with that situation
