MARCH 2019 I SMT007 MAGAZINE 57 Dudnikov: We have a main chemical and reli- ability laboratory that supports all of the facto- ries. The main lab is very well equipped with state-of-the-art equipment. We have every- thing from ICP ionic testing to four-wire Kel- vin where we check on a scheduled basis each plating tank for higher aspect ratios (ARs) and validate the plating quality. We have an in-house SEM with EDX capabilities, so we do our own failure analysis. Each factory also has local labs located in key areas, and then the central lab double-checks their analysis and monitors the SPC. We also have an IR reflow oven and air-to- air cycling, and a dedicated SI lab. We've been doing SET2DIL since I got here, but now we moved to Delta-L testing, and we're going to add a VNA this year. For CAF testing, we do all of our own material certifica- tions. We'll certify materials either to the customer or automotive specifications to supplement supplier data. Then, we have 16 flying probes; six of them have Kelvin on them right now. When we're doing anything over a 10:1 AR, we will test on a Kelvin prober. In addition, we have hipot and inductance testers. Our labs are very well staffed and equipped. This is an area that custom- ers really get excited about. In the PCB business, process control and reliability assessment are the keys to quality per- formance." Another shared resource is drill bit repointing. With all the drilling, we do all our own repoint- i n g . We c o n t ro l based on the diam- eter and hit counts; every pack of drills is serialized, and eve r y t h i n g g o e s through automatic repoint. Our ma- chines will repoint, check the quality of the point, check the overall flute length, make sure it's within the specification of our number of hits and tolerances, and then either reject it or pass it. It's fully automatic. Next, our team sets up the toolkits, and they will move them downstairs through an elevator system. Then, the operator pulls the kit when needed and drills the job. It's a very efficient operation. Factory Two Next, Dudnikov continued the tour in fac- tory two. Dudnikov: Our second factory is four stories, and it utilizes a higher level of automation compared to factory one. Here, we move from In-house drill sharpeners.
