I don't entertain the forum like JAXSUN. I never have played games but for some humorous insights. I, when participating, never complained until management provided only more incentive to advertisers than forum members.
That said, the following is a list of questions every engineer participating on the forum should be asking instead of the obvious supposedly found in the "archives."
1) What are the major issues with solderability especially with "modern" solder termination coatings (cause and effect, process management, FMEA, or whatever)as silver, gold, HASL, tin, platings, etc.
2) What are issues presented by current land pattern sizes, layouts, TCE matching, physical chip properties, etc.
3) What effects are ensured by poor process management without DFM/CE besides the redundant rhetoric expounding question concerning tombstoning and solder ball type stuff.
4) What multilayer PCB requirements must be met to ensure acceptable dimensional stability, laminate integrity, and electrical performance.
5) What issues really are involved in BGA type devices and their corner cracking issues - mostly concerning ceramic types.
6) Why are CCGA type device solder joints more readily acceptable initially and on a long term reliability basis.
7) Why does Dr. Lee's SMQ92 product so much better than the competitions paste - I like especially the J paste with such excellent release characteristics.
8) Why are Tg and TCE characteristics not mutually codependent - for the most part.
9) How is it possible to make BGA's into column grid arrays and why should it be done.
10) Why is it left up to independent companies to determine the most effective pad sizes for BGA's (7095 not yet available) and why is smaller better for BGA's and chip device type components.
11) Why doesn't someone place the advertising stuff in a separate envelope so you forum participants can participate more effectively.
12) Why does all the attention go to advertisers instead of participants who, but a hand full, have departed out of disgust.
13) Why would someone like Earl Moon, and many many others, depart this forum but for not receiving input about their site "hits" (it's a secret known only to management?) so they can share in the site's profitability?
14) Why are there wise asses like JAXSUN participating with only their opinions?
15) There are tons of new questions that should be of concern to all forum members, especially engineers and managers, instead of on-line forums whose questions come only from those interested in solder balling.
16) I repeat, it's easy to get advertisers at whatever price, but you can't make them stay without attracting highly qualified forum members who know what's really going on on the ground floor and in the advanced arenas. 90% of the current participants have real needs that could easily be found in the "archives" but there is no direction to that easily found. IPC has a slick system. How slick? It's just there without blatant banners hung up everywhere hanging up everything.
17) What's the point continuing with over a hundred issues, new and old, so important they are beyond the scope of most here unless the forum's management gets on the ball
