Apex: exhilarating, exhausting, but never dull: an attendance drop stained an otherwise eventful week.Late February's Apex trade show was among the best we can remember for new equipment, materials and software. So much so, we would add, there is far too much to talk about here.

As is typical when a big show relocates, there was no shortage of frowns on exhibitors' faces as they grappled with nuances of the new site, different hotels, unions, and a somewhat dicey neighborhood. This happens almost any time a show moves, however. The upside is the convention center itself, which is beautiful and well laid out. The downsides are the lack of local infrastructure, which is somewhat shocking considering the show was held in downtown L.A., the second largest city in the U.S. Exhibitors cited shortages of higher-end hotels and restaurants adjacent to the convention center, and the position of the center itself, which is at the intersection of two of the most-traveled interstates in the country, making driving to the show a daunting daunt

"This was the best Apex in many years, at least from a lead count perspective. The convention center only served room-temperature RC Cola, but it's a small sacrifice for qualified leads," Aqueous Technologies president Mike Konrad told CIRCUITS ASSEMBLY. Sony marketing manager Vera Chang added that the "quality of customers was good, although traffic did seem low."
Some others were decidedly less enthusiastic, however, but were unwilling to be quoted. In the end, it will be up to each exhibitor to decide whether the attendance merits changes next year. Whether they were happy or not--and we're not willing to project anything based on the anecdotal comments we received, which were all over the map--time tempers frustrations.
RELATED ARTICLE: 'Water Will Seek Its Own Level'
As chairman of the Apex Trade Show Subcommittee, Jeff Timms is something of a lightning rod for exhibitors, pleased or not. (His day job is vice president of Siemens Electronics Assembly, Americas.) He spoke with CIRCUITS ASSEMBLY after this year's show.
CA: What's Siemens' take on all the trade shows that have popped up of late? Is this a good thing--"more stores equals more places to reach customers"--or in conflict with the one-time goal to reduce the total number of shows?
JT: In general, I believe trade shows are a reasonable means to reach customers. They are for sure not the only means, and I do not believe in all cases that they are the best means. They are, however, a way to get face-to-face with a fairly large number of customers in a short period of time. We have to be careful, however, that we do not dilute their effectiveness by having too many with too little impact. I believe a smaller number of shows with larger attendance offers our customers a better value due to the scope of the product offering and the scope of the technical content. We need to strike a balance; in time the water will seek its own level in this area.
CA: As a followup, would Apex better serve our industry if it rotated to Guadalajara or Juarez in order to take advantage of the fast-growing Mexican market?
JT: Not a single Tier one supplier would knock the potential of the Mexico market. However, we are dealing with a different dynamic in that many--not all--decisions to purchase capital are made outside of Mexico. This aspect of the business complicates the selling process for us and the decision process for our customers. In the end, it deemphasizes Mexican trade shows for capital equipment.
CA: It's been suggested that placement OEMs are getting away from the agreed-upon IPC-9850 standard. Do you feel that is happening, and if so, what would you suggest be done?
JT: I don't believe it is up the equipment suppliers to promote the IPC-9850 standard as much as it is up to the customers to demand a specification based on the standard. At Siemens, we typically present three numbers: the specification of the machine running in optimal circumstances (which gives an idea of max speed in ideal conditions); the specification using IPC-9850 (for throughput under known circumstances and design criteria); and an actual customer PCB running the way the customer can expect to see it in their factory. This is where the rubber meets the road and the one that really counts.

JT: I believe that AOI is an interesting market. There is no clear world leader and nearly all the current suppliers have some level of shortcoming (at least, that is what we hear from our customers). By entering the world of AOI we feel we can offer a level of integration that a dedicated AOI supplier cannot. We also feel we understand the placement side of this business better and, as such, can design a process that will be more effective in both pre- and post-reflow environments.
