Dear Sir, We suggest doing only single side V-scroe , not double side . We are able to do it if you like Email :sales@pcbstartech.com Skye: skype: amalia.zeng Wwww.pcbstartech.com

Can you use a conventional router? For boards that small and thin, you could also look into punch dies

oooff... be careful of punch dies. They leave a lot of debris and can stress components on the PCB. If you're using them, be sure to verify stress levels with a strain gauge test. Semi-fractured components can pass test, yet eventually cause latency

You can get a router with a saw blade to handle v-score, but if you plan on doing automated depanel/routing I would probably update my panels to mouse-bites and go with a standard bit based router.

Groovy!!! [Sorry, I always wanted to say that.] As background, look at: * SMTnet Archives * "Pocket Guide to Excellent V-Scoring" and "Scoring FAQ's" [http://www.accusystemscorp.com] they cover all of the dimensions and give a short summary on the

We just had this issue a couple months ago with a single sided FR-4 board which was scored. We found that the design was a factor but also the depth of the v-score. Since then we have re-designed the part further away from the score line. At the same

No Rob you didn't misunderstand, I forgot the decimal point! Lets try this .2" thick (I have built this and yes it was V-Scored) We didn't break any caps on that baby just fingers, that was the wildest VScore job I have ever seen I don't know how the

Hi, Anyone ever perform a DOE on prepreg glass bundle direction or glass bundle grain and how or if it affects PCB warpage and chip component cracking at V-score depanel? Since most FR4 and prepreg has has 1.4 times more fiber bundles in one direct

What is the minimum Tg for FR4 board to consider as Lead Free board? My issue is, I do not know what is the web for the V-Score for a FR4 Tg 180. I use to use a FR4 Tg 140 and there is no problem with it, but since we convert to Lead Free and the

Routing is great for odd shaped PCBs that don't lend themselves to v-scoring. changing from one shape PCB to another is easy. The down sides are you may require custom support tooling and they generate alot of dust. keeping up with the PM will be cri
