October, 2017 Metcal Offers Wide Selection of Soldering Tools


Cypress, CA — Metcal is now offering a range of soldering tools, along with its new connection validation (CV) selective soldering system. CV is the


improve solder process traceability. It creates a performance baseline to quickly analyze soldering perform- ance, identify changes in solder con- ditions, and allow changes to be made. Robotic soldering is


becoming more common- place as manufacturers look to reduce risk and increase productivity. Metcal’s new CV se-


lective soldering system addresses these needs by combining its CV technol- ogy and a new smart in- terface. CV reduces un- necessary dwell time by signaling to the system to move to the next solder joint in the program after a good joint is formed. The system can be easily programmed through its smart interface. Metcal’s HCT2 se-

company’s latest hand soldering in- novation. Built on Metcal’s SmartHe- at™ technology, CV evaluates the quality of the solder joint by calculat- ing the intermetallic compound for- mation and providing closed-loop feedback to the user, mitigating risk in the process. Metcal has released its CV mon- itoring software, which is designed to

New features in- clude a 200W ceramic heater and dual-stage air pump, a replaceable handpiece, and optional bent nozzles for easy access and for use under a microscope.


Metcal’s high thermal demand


(HDT) solution, which comprises a new hand-piece and a selection of thermally-efficient cartridges, has been developed for use with the com- pany’s MX line of power supplies. HTD transforms a Metcal MX


series soldering station into a power- house for applications with high thermal loads, such as dense boards, without damaging sensitive compo- nents.


The company also offers a sol-


der tip cleaner, which removes oxida- tion and extends the life of soldering tips. The easy-to-use cleaner senses the tip when inserted into the unit and activates automatically, saving the operator time. Contact: Metcal, 12151 Monarch

Designing Sophisticated Microfabrication Labs

that we provide them with benches that suit their purposes well, from those who are processing wafers to those who may be doing very ad- vanced research or testing on non- wafer components.” According to Bertagnolli, who


has guided numerous R&D lab ad- ministrators through the equipment design and selection process, the main concern is about setting up the cleanroom and procedures to serve the needs of users. The process is not always well defined and there are many unknowns. “When designing and laying out


cleanroom equipment, it is important to talk with a vendor or consultant with the experience to help you achieve your evolving research goals,” says Bertagnolli. “It is also es- sential that they help ensure it is cor- rectly set up, that the proper safety, operation, and maintenance proce- dures are in place, and that lab man- agers are properly trained to carry these out.” Bertagnolli says that maintain-


ing safety and flexible function for wet processing equipment often requires selecting the most appropriate options from a number of technologies. This may involve various chemistries, tem- perature controls, chemical baths/ dips, ergonomic designs, as well as cleaning, filtration, ventilation, safety, and disposal technologies.


Customized and Modular To facilitate the economical de-


sign and building of a wet processing equipment solution, many users in- sist on a standardized approach with customizable features that will best handle their application parameters. For example, JST uses standard


products and standard methodolo- gies to design and manufacture equipment. The equipment is modu- lar by design for easy reconfigura- tion, should process or product re- quirements change. Another powerful feature: each


unit is designed with software that is capable of performing all tool func- tions, including those that are not re- quired. With this, end users can cre- ate their own process, or recipes, with all sub-routines at their disposal. “We like to give customers


added flexibility by programming their equipment to do everything that it is capable of doing,” explains Bertagnolli. “This enables them to dial in applications, such as chemical concentrations. They can also turn various features on or off, depending

on the process requirements.” Specifying the design parame-


ters for many manual benches may not be as involved as those for auto- mated systems. However, soliciting the opinion of equipment manufac- turers regarding equipment design can be very beneficial. “Certain processes, such as


etching and cleaning, lab managers will want to be flexible enough to ac- commodate a wide range of users and projects,” says Bertagnolli. “We are often asked for tank construction ma- terials that can withstand a number of concentrated acids, so part of de- sign flexibility is ensuring that you use the most compatible materials for the most acids.” “Another aspect to consider is


properly separating, neutralizing, and disposing of all the chemistries involved after use, whether in drains or tanks for treatment or pick up,” she adds. According to Bertagnolli, having


the vendor visit the user’s facility can contribute to equipment design versa- tility that can accommodate changes in lab use over the long term.


Optimizing LNF’s Lab Schweiger explains that the


original equipment design for the new lab areas wet processing bench- es was very specific, and was deter- mined by LNF staff. “We had looked at it in terms of


process flow, from start to finish, not really taking into account the variety of process samples that our user com- munity might be working with, how we’d accommodate non-standard sam- ple sizes, or what the impact might be in total cost of ownership with respect to chemical usage,” he says. Schweiger adds that some of the


new benches had their decks recon- figured once the tools were installed. Several of the earlier benches, some of which were purchased over 20 years ago, were also modified to allow more flexibility to meet the process needs of the user community. “In retrospect, our initial plan for


the deck space, and processing capa- bility of the benches, wasn’t adaptable or flexible enough, and we worked with JST to implement modifications so that the bench decks were simpler, and could provide more working space,” Schweiger concluded. Contact: JST Manufacturing,
