I have a new contract with boards that have straight edges and are good for v-score breakout panel design. However, many of the traces are very close to the edge of the board so I am concerned that the traces could be damaged when we run them throug

Our TP9 UFP machine keeps nicking the edges of A12 tool tips. I think it is because the X axis is bouncing when it comes to the component pick position. When the X bounces it is causing the tool to hit the tape hold down arm. Has anyone ever encount

I haven't heard of heating boards pre-depanel either. We have done extensive studies on cracking of ceramic caps close to V-scored edges and have decided to have our board vendors pre-rout any areas with caps close (

We used a similar part and adjusted the routing so that the front edge of the connector was supported and therefore keeping the connector flat and it not being able to tip forward. I don't know if this is something that you can do with your board?

Hi Randy, From a bare board manufacturers stand point, scoring is probably faster and easier but has limitations. If your boards are square or rectangle scoring will work fine. Once assembled the scored grooves can be sliced apart using what is some

We are leaving 12-18 thousands material when scoring. Several components are cracking during depanelization. The pizza cutter machines out there are either too expensive or too slow to solve our problem. I am looking for a magical solution. In case

| Dear collegues, | I like to have your comments/ experience with various methods of depanelization like routing, scoring, cutting etc. | Any feed back on the equipment used with company addresses will be highly appreciated. | Please identify if pos

Chris: Whatever way you decide to define your pads, use the same type on the component and the board. Non-solder mask defined pad advantages: � No point-of-stress concentration at edge mask and solder ball � No CTE mismatch at edge mask and solder

We did this for BGA pads, but have not thought about other types. So, this may or may not apply for those. Pad defined by:||Advantages||Disadvantages Non-solder mask||No point-of-stress concentration at edge mask and solder ball||Smaller pads have
