I have heard there is a process for mitigating the pure tin issues for 0402/0201 size parts by the use of SN63/PB37 solder print process. Is this true and does anyone have the data to back this up?

Hi all, I do know a little on PCB manufacturing. I would like to know whether using gold on PCB pads can cause soldering problems, both using automation and by hand. We are using a new device, 484-pin, 0.8mm, BGA and 0402 size capacitors. Or it can

I solder LEDs everyday from 0402 sizes on up. I work for an optical company so every product I make has LEDs. Some products have hundreds of LEDs per circuit. The problem is that clear materials are not filled materials and thus don't have the adv

Do you guys have a reference document that lists the number of components per inch / foot etc for all the various sizes - 0402, 0603 etc? I am in need for a project we are working on. Thanks

there can be so many different causes. can be component library height issues. step program z axis offsets - i have seen accidental positive values entered so the components are literally dropped onto the pcb haha. but it does depend on the size of

Does anyone have any industry standard yield factors to load at the component level to account for set up scrap and machine waste during production? I'm assuming there are different percentages used for each package size (0402, 0603, SOIC8, etc) but

Has anyone had success in soldering these devices, in particular devices from a company callede Pycomp. They are 8 way 0402 sized terminations. I have experemented with the printing process, placement verification & reflow profile. Unfortuanlty, I am

We design PCBAs. Our CM assembles the boards for us. So far we have used waterwash SMT process to build the boards. Accidentally, due to documentation errors, we suddenly have a huge batch of boards built with No-Clean process. Although the boards pa

It is not all of the product. It is per separable homogeneous material. A 0402 coil could be broken into at least a half dozen pieces and each piece is separate. Look at the size of a single 0402 joint. How much lead would 0.1% be? Not much. A custom

You have some of the 642s still running? This is impressive. I used to have coupe of these 11-12years ago and I used them for exclusively for simple assemblies with passive components bigger size even back then. Even 0402 was challenge for these base
