Tailoring thermal profiles for the reflow of SMD assemblies
Tang, A.C.T.; Whalley, D.C.; Williams, D.J.
Electronic Manufacturing Technology Symposium, 1990 Proceedings, apos;Competitive Manufacturing for the Next Decadeapos;. IEMT Symposium, Ninth IEEE/CHMT International
Volume , Issue , 1-3 Oct 1990 Page(s):77 - 81
Digital Object Identifier 10.1109/IEMT9.1990.114984
Summary:The aim is to investigate the effects of various types of thermal components (also known as heat thieves/barriers) on the thermal profiles of a printed circuit board (PCB). It is demonstrated that it is practical to apply modeling techniques to the IR reflow soldering process. Results show that the thermal profiles of the PCB can be tailored. This is achieved by surrounding the PCB with different materials, such as copper, alumina, and graphite, in a strip or ring formation. This has the effect of altering the distribution of the thermal properties of the system. Results obtained using the model show that by attaching an alumina strip to the outer edge of the PCB can reduce the temperature differential of the PCB to less than 5¡ãC

Excepting OEM PCB, i.e. Telecommunication, PC Add-On Card, IT Application, Network Device, Multi Layers FR-4 product, we have some outstanding products as follows:

1. Carbon Built on PCB: Apply for Thick Film Technology to make the PCB with buried resistors or touch pad function. It is to reduce cost and increase productivity without any function lessened. We have achieved the filed in memory module PCB and touch pad.
It is easy to imaging a staggering number of resistors in the finished board. We use an unusual technology to embed carbon resistors in our multi layers boards instead of trying to populate all of resistors with external components; it saves space and, hence, increase the speed of system and short the production time consumed.
RAMBUS RIMM PCB: It is a new challenge to make 8 layers PCB with strict impedance control as 28 Ohm 10%, and 4/4 mil trace. As a normal Multi layers PCB, the registration among layers only allows 6 mil of tolerance. This is a breakthrough in the PCB industry. With over a year of efforts, we started the mass production starting 2000.

2. Thin PCB: Less than 16 mil thickness in 4 or 6 layers FR-4 production is another challenge for our production capability. From raw material control, producing inner conductor to lamination, we have to develop many tools to handle the interior materials that are thin as paper. Those materials are mostly used in PC CARDs and some MEMORY CARD, such as the MEMORY STICK, COMPACT FLASH etc. We had produced over 200,000 pieces monthly for Flash Card or Flash Card Reader device in past. The performance is resulting from our outstanding board thickness control and thin PCB process.

3. CSP // BGA PCB: Because the chipset supports high frequency, many requires BGA package, i.e. AGP card, DDR 400 etc. We understand that it is not only for surface flatness, but also for filling VIA holes. Those kinds of PCB are increasing and we expect the quantity will be over 10% of our production in coming years.


4. Special Service: In addition to devote in normal PCB process, our engineering team also provide design support as requested by clients. With cooperation, we complete special process products such as PCB for mobile phone battery with gold wire bonding. The key point is that the surface of the plating needs to be very smooth to reduce the friction between the battery with the mobile phone and the charger. The number of rubbing might be over thousands of times within the battery's shelf life. Therefore, we tailor made a laminate for this PCB, the exterior is extra fine FR-4 cloth to substantially reduce the unevenness of the wrap and weave.
