what is the main concern about this reqirement? Why IPC-A-610c is revsised to this? IPC-A-610c said it is a defect.Solder touches the body of a plastic bodied component, eg SOICs and SOTs. But D version think it is acceptable. WHY? I thought "plasti

Hi SMT World, I am facing a technical challenge related to an SOIC 14lds with thermal pad on it's belly that needs to be soldered onto PCB, together with leads. It is a 50 per board, expected 80% solder load on every one. We have some units without

Excessive bridging on SOICW-20, -16, SOIC-8, -14,-16. I've got a board, 4" x 6" w/ SOICs on bottom-side for wave solder. I've checked topside board temp for flux activation, wave height, wave surface with the glass check-plate going from 1" to 2" spa

My company is considering purchasing a depaneling press from Pioneer-Dietecs. Our initial evaluation has been very positive; however, in a recent meeting a question was raised about the amount of stress induced in the pcb/components during depanel.

Trying to find out if there are any data/articles/references out there that looks at the reliability of using SMC�s over interconnects(connectors). The dilemma is having a daughter card with a board-to-board connector vs. having the components (dis

We have been using Tape and Reel on our GSM for the SOIC-8 packages for a while, and it's working pretty well. Less operator error, less reloads, less jams (provided you take good care of the feeders) and LESS TUBES STUCK IN MY VCD SEQUENCER!!! I hav

We currently use Siplace P & P machines and in the main prefer to pick SOIC ICs from stick vibratory feeders. Our reason for this is that we can fit 3 stick fed devices into the same space as one reel fed SOIC. This reduces the amount of setup we hav

I just started a design where I will be placeing smt parts on both side of PCB. 50 parts on top side ranging from 0602 to SOIC8 and 4 SOIC LED's on bottom. How can I assemble with parts on both sides ? I have P&P,stensil printer, relfow and solder w

There is no standard for what you're trying to accomplish. We recall a similar thread on SMTnet. In it, a poster suggested: "Call them: 1206T.5, 1206T1.0, SOIC16, RESNET16, SOIC16T5.0, ALCAP4, ALCAP5 etc., where: T means thickness but for the ALCAP

We are in the process of establishing a design for thief pad associated with SOIC on the bottom of our assemblies. We are seek advice on design and alternative to their use. Best Regards, Charlie
